Good to see someone checking out something and giving it a second chance. Yeah, reboots/reimaginings/retoolings like this are sometimes very hard to swallow and a usually a tough sell to those that grew up as die hard's of the original.
I'm a Trek fan - in so much that I've seen all the films (much more a fan of the early films - I remember coming home from the theater in 1982 mumbling 'why'd Spock have to die'), enough of TOS to have a clear grasp of it all, watched TNG fairly religously every Sunday at noon during it's first run. TNG just doesn't hold up that well for me. I gave DS9 and Voyager a chance, but it never really stuck... may've watched one episode of Enterprise.
I both love and hate this movie. I guess a lot of people might be like that.
I don't care for Chris Pine and his portrayal of Kirk. But, in all honesty... the 'new' Kirk was a pompous, arrogant, ******* - probably a lot like the TOS Kirk would've been. Well, that and his hair... damn, his hair sucked. Chris Helmsworth may've made a better Kirk - if they could've taken 30 lbs off him (but, he became an amazing Thor).
The new Enterprise - at first look, I loved it. But, after living with it for a while I'm still not sure what they were thinking when they designed the bit where the nacelle struts meet the body. ..and yeah, it was a little to chic - the Enterprise from the first few films was perfect.
The story - Nero and the Romulans - was all just throwaway bits to get us to the characters and get them all on board. Yeah, like lots of movies there's the bits that scratch our heads and write off as fate (Kirk meeting old Spock)... but, jettisoning Kirk off the Enterprise is just a stupid, stupid plot device and as unlikely as it would be for him to stumble on to old Spock, shooting him off onto Hoth is just ridiculous... I can accept conincidence/fate - but, that was just stupid.
Karl Urban was perfect. Quinto was decent enough. Pegg wasn't quite the Scotty I knew, but I'll take this new Scotty. Yelchin and Cho worked well enough (loved Yeltsin's accent). Uhura wasn't all that for me...
But, overall - the big picture worked for me. We got to see the beginnings of the chemistry that made Star Trek work. Bones' banter, Spock's logic, Scotty giving her all she's got and Jim Kirk defying the odds.
Hopefully the next movie will give us all that with a better overall story.
