I didn't really like it, and here's why. If I wanted to watch an hour and fourty minutes of Tom Cruise yelling at kids, I'd stalk him when he takes Katie Holmes to the Scientology center. If I wanted to watch twenty minutes of Tom Cruise hiding in a basement with weirdos, I'd go to the Christmas party at Brooke Shields' house. If I wanted to watch aliens dying of some terrible unknown brain disease, I'd watch that one episode of Oprah.
Yes, this episode of Oprah. Seriously, its about as bland a movie about alien invasion as I've ever seen. I mean, at least Signs had some side-plot action about Mel Gibson's dead wife and his brother and god. This is just Tom Cruise running around and hiding, being one of the only survivors of attack after attack, and then being cool enough to blow up a "tripod" with some grenades in the alien ships "anus". Then the biggest RIP OFF of the movie is that his stupid son survives, when he is CLEARLY a moron and everyone hates him. Wait for the video... (or Armageddon)
