I thought that, overall, it was great. I though the actors that they chose were perfect, and I really liked the acting, special effects/cg, music, story, etc. There were a couple of things I'm not sure about though: 1) Uhura and Spock?! come-on... really? 2) the whole alternate time line ending. I mean, I understand why they did it... it gives them the freedom to follow a whole new set of adventures for the same characters, but doesn't it sort of make everything that follows in the ST universe irrelevant?
