Well, I finally saw it. I don't know why everybody was so scared in the movie! Everybody was jumping at the stupidest parts.. Oh well. I thought that it was a good movie... Too much little humour, IMO. I really liked the aliens, but I wish that there would have been more scenes with them. And that "home video" was crap, IMO. It wasn't scary at all. About everybody in the theatre jumped, but I laughed because it looked like Yao Ming.
Overall, great movie. 4.5 outa 5.
