Saw it the other night. Sort of had to with a 98% on Rotten Tomatoes. I normally don't like movies with that time travel premise (perhaps the only exceptions are Harry Potter and 12 Monkeys) but aside from that I enjoyed it. It was a satisfying experience though the plot had much of the same campiness as the original show. The casting was pretty spot on. They are indeed trying to create a new franchise though it that might be weird having a series of movies where the actors are all doing impressions of the previous crew. This one was fine as an homage and I enjoyed the plentiful references, but not sure if they can do it again. Good special effects which is a first for star trek. Still lame a$$ fight choreography. Sulu's (played by Harold sans Kumar) allusion to fencing (see Naked Time from the original series) could have been awesome but was poorly executed.
An easily likable (hence the 98% rotten tomatoes score) but not a great movie.
Final Grade: B
