As a long time Trek fan (I first started watching with my Dad in the early '70s as a child), I was VERY anxious about this film. Given the track record recently, Paramount is considered to be as close to the Anti-Christ in the opinion of many older Trek fans, between the mediocre scripts, re-use of ideas and constant F*****G around with continuity.
This move KICKED ASS! I can accept the overall story regarding why THIS Star Trek is different from the Original Series in the '60s, the acting is great without being parodies of the original actors (okay, Chekov pushes this one a little) the updates to the look (with one BIG exception, in my book) are understandable and fit the story.
Leonard Nimoy's role feels like it belongs in the movie and wasn't just pandering to the older fans. I know Shatner wanted a role, but I don't see how he could have been worked in, unless he played a Kirk family character, such as an uncle. Given the current story line from the previous movies, Kirk is dead, period.
They now have clean slate. Here's hoping they use it wisely.
Okay, the big exception I had regarding the changes to the look of the technology was the engineering room. Come on! Big steel cylinders with tubes and hand turned valves? HUGE open areas for no obvious purpose? Catwalks all over the place for no real purpose either? Seriously, the engine room looks like something from the middle scenes of an average action adventure movie, NOT the engine room of a 23rd Century starship. (Actually, it was filmed in a brewery!) Okay, that's my geek rant over with.
