Elysium- Pretty cool sci-fi. I liked it and didn't feel that I wasted my $8.50. If I have to rank against similar recent releases, not as good as D9 or Pacific Rim, but way better than Oblivion. Not terribly long either (just a shade under 2 hours). The action is pretty well paced. Blomkamp gets a lot done in a short amount of time, which is refreshing when every other film seems to be drawn out to 2 hours and 30 minutes regardless of whether or not it has the content to fill that time.
I liked the story, the action is good without being distracting. The only gripe I had with the movie is Matt Damon. Don't get me wrong, I like Matty D. The character just seemed like he should have been a lot darker and Damon has such a nice guy persona. The main character's name is also Max, which sounds like Matt, acts like Matt, and looks like Matt. So basically it felt like you're watching Matt Damon doing all this stuff. Rather than the guy he's portraying. Which takes away from the film.
