The plot makes no sense whatsoever. (SPOILER ALERT)

Rating: 3/10 (11 May 2009)

I'm not going to hit this from a scientific perspective. That would be too easy and would just invite others to castigate me for not "suspending disbelief" during a fun summer sci-fi. No, this movie sucks on a very base level. The first, and most disturbing part of the movie is the villain, Nero, who I think is the worst villain Hollywood has given us, and Hollywood once gave us Arnold as Ice Man. Nero is awful because his motivation makes no sense whatsoever.
As the story goes, Nero is furious at Spock, and by extension his whole race of Vulcans, because Spock did not get to Romulus' star in time to save it from super nova, which destroyed his planet and all those he loved and cared for. In the process both he and Spock are sucked into a black hole and spit out the other side well in the past, except at different times, Nero 25 years before Spock. In waiting 25 years for Spock to come through the black hole as he had, Nero and his crew seethe with rage and plot their revenge against Spock and his evil race of Vulcans.
But why? Did Spock create the super nova? No. That was explained as a natural disaster. Did Spock try to save his planet? Yes. In fact, he had every reason to believe that he was going to die in the process. After failing to stave off the super nova, he was sucked into a black hole, which is assumed to destroy anything entering it (after all, black holes literally crush atoms to the point of not existing). Personally I think that makes Spock a hero to the Romulans! Having a vendetta against Spock and the Vulcans would be like tracking down and killing the family of a fire fighter who died in your house while he tried to save your wife and kids. That makes no sense. None. Last, Nero is now in the past, no? Why doesn't he just go about saving his planet from destruction? He's got the "red matter" to do it.
The other thing that ticked me off was the silly string of "accidents" that put a gang of 22 year-olds in command of the Federation's flagship. Do they not have even a single 40 year-old who has actually been in space before? It's even worse than that if you think about it. Before the ship takes off Kirk is about to be booted out of Starfleet—but now he's put in charge?
I'm willing to suspend disbelief in sci-fi movie, but there's a difference between suspending disbelief and watching a movie like I'm a 3-year old. 3 stars out of 10.
