Wow. I must say that I'm very impressed with this one. I didn't see Frontiers and had no interest in seeing Hitman but this film is definitely in the top ten films released this year. If you're expecting a lot of action then don't watch this because it'll probably be boring. It reminded me A LOT of Blindness in the way it portrays how people can react to a natural or man made disaster. It's one of the better psychological horror films I've seen recently. Check it out if you're into that kind of thing.
