I'm willing to reserve judgement on this until I've seen the finished product. Trailers can be designed to showcase the best of the movie or in some cases, show very little of the actual story. Whatever the case is, this is a highly anticipated movie and will live or die by the audience reaction.
Times do change...we no longer accept the day-glo colours of the 60s and if the Enterprise was designed exactly as it was back then, we'd be mocking the movie for trying to showcase a time long past.
I hope the movie does well...I've seen positive reactions and some negative ones surely we should be judging it on the finished product not what the spin machine known as the internet deigns to give us?
There have been far worse things than a series reboot - labouring under the impression that CG imagery is better than real sets and real reactions, for example. Did Lucas, for example, air almost 30 minutes of his unfinished movie to movie critics to get reactions? I think not. Chris Nolan was lambasted initially when he took on Batman for 'being a Brit who knew nothing about an American icon'...look what's happened there with his reboot.
It shouldn't matter that Abrams is a TV writer/producer/director. If he has been picked for his vision, then he should be able to bring his vision to the screen without someone screaming that 'he's raped my childhood!' How does that work, anyway - is Abrams in possession of a list of everyone who's seen Star Trek? Is he now going through that list to work out what he can screw up for that person individually, so much so that they can never watch Star Trek again? Is that the same for Lucas? If anything Lucas has screwed his own history up more than any of ours...he's the one in denial over the original path of his story - it's not like we had any say in any of the storylines given in the first place.
Anyway, enough ranting...I'm not going to be upset if the film isn't what I expected it to be but I also won't be running around saying it's not Star Trek. It will be Star Trek, but one for this generation of viewers and we're going to have to accept that movies are made for the current generation, not the past.
