Maybe you had to play the game to like the movie...

Rating: 1/10 (12 May 2006)

This movie was by far the worst movie I've seen recently. The "monsters" weren't really scary, they were either gross or comical. The acting was certainly nothing to write home about. A cameo or a scene that was actually believable and/or scary might have been nice, but I doubt they could have really saved the movie.
The fact that it was based on a video game, which I did not know going into the movie, explains a lot. While I can see it being a decent video game, it was not a good movie. I think the only people who can delude themselves into thinking that this was a good movie are those who were already fans of the game. Unless you are one of those people don't waste your time or money.
