Excellent

Rating: 9/10 (2 September 2012)

I am not a Trekkie even though I followed the series and watched the films. I've watched this particular instalment of Star Trek 5 times already (for various reasons, sometimes not by choice...). I found myself enjoying it immensely every time. It's true that some coincidences and conveniences are somewhat far fetched. You might find it difficult to enjoy the film if you find yourself hung up on them to much. I didn't have a problem with it. I let my self be entertained by fast paced action. Star Trek, and most science fiction films, have to work on the far fetched to begin with so I'm OK with it.
Response to some of the criticism I've read:

Hard core Trekies may have a hard time "swallowing" the alternate Trekie-reality in which the film is based on. I think this film makes some effort to part from the previous works.

(spoiler) Why go (Nero) after Spock instead of saving is planet?

Please, Nero is deranged. I think the plot establishes that quite well. He goes after Spock for what he believes to be a just revenge. Also, they are 25 years (?... don't remember exactly anymore..) away from the event, which means that there is ample time to deal with Spock AND try to save his planet. Of course, if he manages to prevent the disaster then he won't go back in time and the paradox of time travelling is set. This is why time travelling in films (or anywhere for that matter) is never consistent and leads to holes in plots. If you have a problem with time travelling in films, stay away from this one.
