Well I was a bit late in seeing this film, but I enjoyed it. It was a bit slow at the start with the high school drama/teenage angst, but it picked up during the last half. It is not a film for everyone, but for the scifi crowd it was not too bad. The film seemed to have a bit of trouble figuring out what type of film it was going to be. There are a lot of questions that are never answered (like why do they have to be killed in order? why do they have to be killed before earth can be invaded? why are there so few invaders? etc).
Many will probably want to wait for the BD to come out to see it. But, if you want to see a movie in the theater it is not bad for a February release.
