I watched this movie three times this past week. Yes, folks. THREE TIMES. It was that good. If you haven't seen it, I SO encourage you to rent it (or buy it). It has some great action. Usually I'm not into movies with a ton of action, but this movie has just the right amount. If you're into the Resident Evil movies, then you will love this one (and even if you're not).
The main characters are played by Denzel Washington (oooooooh yeah) and Mila Kunis. If you want a movie with a great twist, this would be the perfect one.
