This could have been a great movie, but the youngest daughter got on my last nerve throughout the entire movie. Whoever wrote her story messed up the movie. Her ways were not always warranted.

Half way through the film I kept thinking this is like Skyline, a film I hated, but good. As it went on however, it just got better and better, the twist comes as a huge surprise, one I certainly never expected. This has been advertised on a huge scale, and is I would say better then the adverts would have you believe.

Such clever writing, it's sci fi, but so different to everything I've seen in a while, clever and imaginative, seeing the other side for a change, which makes you think about the film differently.

Very well acted, with some great special effects. It's not perfect by any means, there are times where it seems to jump about so much I didn't know who was who, or what was happening. It really didn't matter though as the story itself is very, very enjoyable.

It's been a while since a film has surprised me, particularly a sci fi, but this is excellent 8/10
