My favourite Doctor is Tom Baker obviously.
I grew up on Doctor Who videotapes, and saw a lot of Jon Pertwee, Tom Baker and Sylvester McCoy.
I loved all those old Doctor Who videos. My dad has the Peter Cushing movies on DVD too. And the Paul McGann Doctor Movie bit.
They were all great. I don't mind the how cheesy they are, however cheesy they got I could still laugh. When I really got going, I didn't even notice the bad special effects, so some of the 'cheese' I didn't even notice.
But for some reason, it doesn't work in the series that have Tennant. It feels wrong. I can't figure it out though. Why did the return of K9 work so well? That was undeniably cheesy.
So why didn't I like it when we had three stereotypical witches that used magic words (which was given a really shitty scientific explanation) to open a portal which was closed by quoting from fucking Harry Potter? I can't wait until Doctor Who defeats the Daleks by playing the Artic Monkeys at an absurd volume.
That episode would have been better without trying to explain the witches with science. "The Satan Pit" was a great episode, it had Satan trying to except from a prison caught in the gravity of a black hole. They didn't try to explain why they had Satan in a sci-fi program trapped in a prison caught in the gravity of a black hole though.
That was good Tennant.
The 'Absorbaloff' episode was just an embarassment. The ONLY redeeming part of that episode was seeing Tennant and Piper running around with buckets of water to destroy an alien. As far as I can tell, the alien was allergic to water thrown at it from the right coloured bucket. That's the perfect explanation for a doctor who episode. That part was cheesy and I enjoyed it. It really didn't need that ending either. Perhaps had they left her dead, it would have been better. The third person narration was a good idea wasted on a really badly executed story with characters that I just wanted to die in the most horrible way possible. I guess they did, but that didn't make me feel any better, especially since the two most annoying characters outside of Peter Kay survived. Sort of.
The last episode was great, with the pig faced people and the bad accents and the crappy looking Dalek person. I actually loved that one.
Outside of the classic series, my favourite Doctor Who 'episode' is a web cartoon starring Richard E. Grant as the voice of the doctor.
You should check that out if you haven't already.
