The science was egregious (I noted that Roger Ebert gives more signs of knowing science than the entire Star Trek franchise) but... Trek is fantasy; I have less forgiveness for the plot holes. People should make sense even if the universe doesn't.

I realized last night the movie only barely passes Bechdel's Test (brief conversation between Uhura and her Orion roommate about her work, which clues Kirk in); akashiver and I disagree about whether that matters.
