I just Screened this on Tuesday, I did not think the storyline was too unique. The acting was on par with Damon's past work, but what this reviewer fails to tell you is to sit way back in the theater. This movie is made to look like it was shot on location (i.e. Blair Witch, Cloverfield). The shaking of the camera almost never stops, the camera moves very quickly at times and there are lots of fast camera zooming and panning. The movie made a number of people at the screening sick, I was sitting about seven rows from the front, people sitting near the back did not seem to have much of an issue. I screen way too many movies to even count and this is the first time I've experienced sickness (Not even in 3D), so be prepared!
