I've watched Star Trek since I was a wee lad, and as I've gotten older I crave more intelligence from my science fiction. This has begun to color my view of extensions of Roddenberry's genius franchise.
Acting-wise, nobody is too 'out-there,' nor does anyone fall flat. Exciting writing had me laughing and wrapped up in the excitement of the film.
However, it works well as a action film, with very few of the cerebral issues that has me even still loving classic Trek. This "Star Trek" instead rebooted with a time traveler with a spot of Inigo Montoya issues.
To sum up, it's a popcorn movie in the same vein as Classic Indy or The Mummy. So go, have a good time.
