So Netflix UK had season 1-6 of NuHu on it so I basically binge watched all (most) of it so I was adequately prepped for the new season. Spoilered for some actual spoilers and also for length.
Series 1
I'm probably biased because it was the first time I'd regularly watched Doctor Who, but of the three modern Doctors (the only ones I really know properly) Eccleston remains my favourite Doctor. He's dark, damaged, angry from the Time War, and it means that when the show has its moments of wonder he finds a real joy in it just like the viewers do. I'm thinking specifically of the two-parter in World War II, when he's overjoyed that 'Just this once, everybody lives!'
I also really like Rose as a companion. She's not just along for the ride, a damsel in distress - she's strong, she's clever and streetwise in a way the Doctor isn't, but also flawed - hence the episode centring around her father. This is also pretty much the only season that I happily watched every episode of without any of them being boring, irritating or flat out stupid. Horror doesn't usually affect me much but the World War II two-parter (by Steven Moffat, surprise) scared the shit out of me the first time I saw it, especially when wotsisname from One Foot In The Grave turned into one of the gas-masked bastards. I also quite enjoyed the Slitheen as new beasties. The first Dalek episode is brilliant (bringing some new elements to the Daleks instead of having them just as relentless killing machines) with real darkness in it. The reality TV episode is a little bit iffy, although it is quite a funny concept, but it's dated, BADLY. Especially having fucking Ann Robinson-bot in it, Jesus Christ. At least Big Brother still exists.
It is slightly annoying that they spent so much time on Earth.
Series 2
In comes David Tenant as the new Doctor, a Doctor I often found quite irritating - he's quite a know-it-all, a bit of a goof (I love goofballs but not so much as the hero of a show I'm watching) and the constant references to him being attractive are irritating and the main hallmark of what I disliked over the seasons leading up to Peter Capaldi. Especially annoying given the Christmas Special really suggested Tennant was going to be an even more pissed-off Doctor than Eccleston, especially when he destroys the Prime Minister.
At least we still have Rose, though. There are some great episodes - The Girl In The Fireplace is a great one, The Impossible Planet/The Satan Pit was quite scary in places (although that's probably due to my Christian upbringing). Also the closing two-parter (DALEKS AND CYBERMEN AHHHHH) was pretty great, again a new spin on the Daleks by having this small cult of named ones with actual personalities instead of just being drones. Gets rid of Rose Tyler, which I found a bit gutting. However, that fucking Torchwood woman somehow surviving being a Cyberman and CRYING THROUGH THE MASK OF THE SUIT may be one of the biggest 'fuck yous' to an audience I have ever seen.
There is also Love And Monsters, which may be the most detestable episode of the show I have ever seen and ends with a fucking dick joke.
Series 3
This is the season that got me to stop watching, largely because I found the premiere episode dreary and unoriginal. Martha is pretty much a blank slate, but the new aliens in it don't help. The Judoon are an okayish concept, interplanetary police, etc. etc. but they're just fucking space rhinos, and are really symbolic of my other key issue with Russell T. Davies as a show runner - on multiple occasions he thinks that he can justify a new alien design as just an Earth animal IN SPACE! Space rhino! Giant space wasp! Big space beetle! Fish humanoids! Sigh.
There are also some pretty shitty episodes. The Shakespeare one sucks, the Daleks in New York ones suck. But there's also a clutch of really fantastic ones - the Lazarus episode is great and delightfully creepy, and Blink (hello again Moffat) the first time I saw it was one of the scariest things I've ever seen, despite having no actual gore. Also one of the few episodes to really use the time travel thing to its full potential without just kind of being 'TIME TRAVEL MAKES WEIRD SHIT HAPPEN SO SHUT UP'. Human Nature/The Family Of Blood is a weirdly mixed pair of episodes. It has some great proper acting from Tennant when he has to decide to kill John Smith so that the Doctor can live. However it's also got some confused ideas. When The Doctor re-emerges he despatches the Family with relative ease, raising the question of why he bothered hiding in the first place. There's an unnecessary racial subplot that goes nowhere, and one of The Family (the younger lad) is overacting to a preposterous degree compared to the other three. Jessica Hynes' acting in it is wonderful, but she is someone I've loved as an actress since Spaced. Nitpicky moment - why couldn't The Doctor have a 1913-suitable hairstyle? He could keep his hair the same length but just slick it back. Why did no one notice that his hairstyle looked like he had just got out of bed? Not exactly in style for 1913.
Then there's the Master episodes which are amazing, partly for the writing and partly because Jon Simm, just Jon Simm. Jon Simm is glorious. Camp, crazy, funny, but also unremittingly evil, like Jack Nicholson's joker. Jon Simm. JON SIMM. 'It's a gas mask... because of the gas.' I also love that the Master has his own musical score based on the drumming, which is delightfully creepy and a great piece of music in its own right. And despite John Barrowman being surprisingly irritating in real life, I never get sick of Captain Jack Harkness.
Series 4
OH CHRIST IT'S CATHERINE FUCKING TATE
...and she's not bad. Catherine Tate is someone else who I found irritating and I was going to give the new season a chance until I saw she was in it, at which point I basically stopped watching until the specials in 2012/13. I wish she hadn't used that annoying accent, but the character is actually quite well written and significant, much more of a worthwhile companion than Martha was, contributes a whole shitload more.
However she's not helped by an opening episode about a weight loss pill. Giant. Who. Gives. A fuck. There's not many episodes that stood out to me in this. The library ones are pretty good, and hey look it's River Song.
The final three parter makes the entire series worth it though. All the old friends come back for another go round, even fucking Sarah Jane, and the sheer velocity of the story across these three parts had me completely hooked in to watch it all back to back. This was really a fantastic three parter that got me properly invested and I love that it focused in on Donna rather than The Doctor himself and gives Rose a much better ending than 'hey, you're in an alternate universe, now fuck off.' And I love Wilf. Wilf rules. Also I love Mickey. Real character evolution from him, going from pretty much a useless gooseberry to a heavyweight player in storylines at times.
2008-2010 specials
I dunno what the fuck was going on for these few years, but hey whatever. These specials were a real mixed bag for me. Without a companion as an entry point we're left just with Tennant's Doctor, who I don't really like that much. The Next Doctor was okay, Planet Of The Dead bored me to tears so I didn't even finish watching it.
Then there's the Waters Of Mars, where the Doctor finally has the arrogance to play with fixed points in time, and it backfires. A quite thrilling episode.
The Master returns (in pog form) and the fucking Time Lords! I had no idea this had even happened, that's how out of the loop I am. I love that they finally explained the drums, but I much preferred the Master as an insane overlord rather than as a scruffy street urchin who has super powers for some reason. The closeout for all of the old supporting cast from The Doctor by visiting back through time was a lovely little moment, quite a tearjerker, although I still can't stand the 'I don't want to go' bullshit.
Series 5
I can't believe how much the tone and direction of the show changes from the instant Moffat takes over. It really doesn't even feel like the same show at all. Which is in some ways a positive as it's a real clean break from the Davies era, but I'm not sure whether I actually prefer the way it now looks. It is certainly a lot more cinematic, though. And at least they were off Earth a lot more.
I don't much care for Matt Smith's doctor either, although he is at least an improvement over Tennant. Also, in this season, Amy's kind of a bitch to Rory, behind his back and to his face, something which clearly still irks him even in series 6.
There weren't many episodes that really stood out to me but then that's because Moffat puts more emphasis on the ongoing arc of things than Davies did. There are still some standouts - the Churchill episode is pretty cool although I have no idea why we needed to hear Churchill say 'buggering.' The vampires episode isn't great. I loved the one with the Dream Lord - the guy playing him was perfect and the reveal at its ending helped me like Smith's Doctor a whole lot more. The Hungry Earth turned into a decent two-parter but had the most disheartening setup I've ever seen for an episode (CARNIVOROUS EARTH OH MY GODDDDD). I loved James Corden in this, and I usually can't stand the guy at all. I haven't the faintest idea what the fuck happened in the final two-parter of this. Also Moffat really does use death as a dramatic crutch (more on that later).
Series 6
This series has by far my favourite Christmas special, partly because Michael f'ing Gambon and partly because I loved the story and the way that the story shifts with the time travel, making Gambon at first a brighter character, then a darker one, before the final adjustment.
I hated the opening conceit of the Doctor getting killed. This is partly more of a criticism of the way TV shows and the media interact these days than anything else - I hate that nowadays the new Doctor is such a big deal that it has to be announced in advance instead of done as a surprise like Tennant was. Obviously the Doctor survives or there wouldn't be a show. Obviously he doesn't regenerate because no one had been announced to replace Smith. This was also an irritant in the Hitler episode when The Doctor is poisoned irreversibly by River (who became increasingly annoying) but obviously he isn't because no he doesn't die at all because he's the fucking Doctor and he already got killed in the opening episode. Oh, and Rory dies all the fucking time. Stop it. Just, stop it.
That aside, I adore the opening two episodes of this season in every other element. The Silence is a fantastic concept, the aliens are fucking cool looking (simultaneously influenced by G-men and the bigheaded little green men of old) and the ex-FBI agent is a character I'd love to see more of. I also love the little reveal that he has a black, male lover at the end which Nixon doesn't know how to react to (also props for not going the easy route with Nixon at any point).
I also really liked A Good Man Goes To War, because the Doctor makes an actual mistake for once. Not an arrogant, 'fuck this I can save people' mistake like Tennant's Doctor, but he is just outsmarted by someone (another thing that never or rarely happened to Tennant, who had the answer to every question whether it had been asked or not). I loved all the previous one-off characters coming back and uniting, and the Sontaran nurse was hilarious, especially when he's working on the young boy's injuries and expresses a desire to fix him up good as new so that one day he can kill him on the battlefield instead. I enjoyed 'Closing Time,' Corden entertained me a lot again and I loved seeing The Doctor just, well, interacting with the real world, and especially that woman who thought Corden and the Doctor were a gay couple. Not sure how I feel about Corden overcoming the Cyberman assimilation through the power of a father's love or some shit.
Finally, a series finale that isn't about twelve parts long, but I didn't find it especially inspiring. Because, again, OF COURSE the Doctor doesn't really die.
I got sick of River. Sick of the flirting. Sick of the mysterious bullshit. I just don't want sex in Doctor Who at all, thanks. It's not for that. I'm really hoping tha Capaldi's doctor doesn't have any fucking irritating love subplots. How does that even work? Is he humanoid? Does he have a dick? And you know what, I don't even want to know the answer to those questions!
I did find it a bit weird that Amy and Rory are absent for multiple episodes at a time. Are they the fucking companions or not? Come on now.
