It's not unique though; the technique has been used several times before. I do not think if they had used several point of views to show different perspectives on the same situation, like in Crash, the movie would of made sense. Questions could have been answered, the movie could of been longer, and maybe I would of enjoyed it.
I would of loved for the annoying cast to die in the first 20 minutes, then show the happenings from a different point of view; perhaps that of a combat photographer for the military who somehow reveals information to us about the monster. Then the two storylines converge and use knowledge gained from both to realize a common truth.
The only good thing about this movie were the effects. You can't even say it was a movie, because it wasn't. It was a 1 hour long showcase of special effects and nothing more.
EDIT: I'm 18. I hate our generation. Everyone is so dumb. Only this generation would say that this is a good movie. It wasn't. It was built up to be, 'The next great american classic horror movie', and we all wanted to believe that so much we've been tricked into thinking what we saw was good.
