Really? IMDB has a lot of positive commentaries (as well as some negative). None of my friends/family that have seen it have had anything really bad to say about it. I think the people that are knocking this film are not really understanding it, or were expecting something completely different. IMO, this film is NOT about a monster. Sure, the monster is the driving force behind everything that is happening, but to me, this film is about the first person experience. Who cares if you don't get a full frontal shot of the monster? Who cares where it came from? Its really not about that.
Also, a lot of people complained about the ending. Why does every movie have to have a happy ending? Why do all the questions always have to be answered? If you have to have everything spelled out, you should stick with Michael Bay and Roland Emmerich films.
All I can say, Worm, is that you're missing out if you don't see this one in the theater.
