This movie is a modern B-movie that does a lot with a little. In several places the acting is actually pretty good, and the practical effects on many of the aliens often works well. Some of the action scenes, though highly derivative, are surprisingly fun. That being said, it unfortunately doesn’t amount to more than the sum of its parts and the flaws intercut with the gems bring the whole movie down together.

Closest comparison: It’s like a B-movie cross between Independence Day and District 9.
