I loved the movie, im a general scifi fan, and i don't care about canon wether Star Trek, Star Wars or Stargate.
It has been a straightjacket for startrek way too long, glad JJ. Abrams got rid of it.
There's enough of the old trek in it, with all the references etc.
If you are a rigid member of the startrek cultmovement you won't like it (and who cares, you are not the one JJ.Abrams aimed for anyway).
If you like a good movie with action, humor a decent story and acting no matter what the subject is, this is better than any of the previous trek movies with the exception of "The Wrath Of Kahn" (which can never be beaten, Ricardo Montalban was the best adversary the enterprise ever encountered).
I realy liked the movie and i just love that new ship, it just looks way better than any other enterprise.
More up to date and a little meaner.
mmmm, I hate to rain on your parade,
but James T. Kirk was not born in Iowa, not even on earth according to this movie 
He was born on a shuttle , he only grew up in Iowa
