The concept is kind of cool, but the film itself? Just awful.

Rating: 3/10 (13 January 2006)

I really don't understand what attracts so many people to this terribly written, terribly acted, terribly filmed piece of trash. When I saw the story for this film, I really thought it would be the best horror movie of 2004. It sounded awesome. Then I saw it, and I was utterly shocked at how bad it was.
As I said, the concept was good. I also thought the twist at the end was pretty cool. Completely unbelievable, but cool. That's it. That's what keeps it from being a 0.
The acting is the most atrocious I've ever seen. It's like amateur hour. It's like the director gathered a bunch of teenagers who've never seen a movie before and said, "Now act!". Cary Elwes and Danny Glover are generally not bad actors, but something happened to them in this film. Cary Elwes is completely unconvincing. What's worse is that the character of Adam is played by Leigh Whannel, the guy that wrote the thing! He's a terrible actor too.
Really, this is a terrible film and it does not deserve the credit it gets.
