Personally, I am going to have to say Children Of Men. This movie was not hyped too much and was not met with too much praise or criticism. I thought that it was fast-paced and kept you on the edge of your seat the entire time. Not only this, but it was filled with plot twists that keep you guessing the entire time. The best part of the movie is a scene toward the end where Clive Owen is running through an urband battleground with gunshots and explosions all around him. This scene was done entirely in one take for almost seven minutes. At one portion, someone in front of him gets shot and blood actually stains the camera and they still keep going. It's just amazing.
