CAUTION: MOVIE SPOILERS AHEAD
Oh, don't get me started on the changes they've been making. I agree with the whole altered-time-stream thing (had to happen), but I absolutely HATE the relationship between Uhura and Spock. She's the only character they got wrong. Send Saldana back to Avatar and find a more motherly Uhura who can sing.
And since when would Uhura be the person sent down to help Spock in battle? It was the same disconnect as when Mrs. Weasley suddenly became the warrior woman equal to Bellatrix.
In the original Wrath of Khan, I sobbed when Spock died. I wasn't even moved when I realized they were recreating the scene. Good action, but outcome too predictable.
Sorry. I'll stop there. Still, I loved the movie.
