The special effects are good. With the exception of Kirk and Spock, the characters are not fleshed out. If you think well of the original Star Trek movie, you may not like this one - I didn't. The move has to have one of the most absurd ideas for a weapon ever ... Red Matter. You have to be kidding!! If you can ignore eveything Star Trek in the past 40 some years, it's a passable movie.
The movie starts well. One of the movie's themes is the tension between determinism and randomness. At the movie’s beginning, Cage's character believes that events occur in a more-or-less random way, but by the end he moves to the other extreme. The problem is that while determination may lead to "knowing", it renders attempts to change what will happen ineffective. The ending is absurd. It's as if the writers painted themselves into a corner and so introduce a "deus ex machina" to resolve (and I use "resolve" loosely with sarcasm) the final bit of knowing. If you are like me, you’ll walk out grumbling that the director and writers totally wasted a good premise with an absurd ending.
