My personal favourite is the second one. I just think it has the best story, it uses the 'game' gimmick the best. The traps are really good too and the shock at the end is so surprising, I seriously didn't see it coming.

The first one. I found it by accident. It gave me nightmares. The fact that it could actually be done.

The original. Anything after the second one is a waste of time.

First one. It was so original and brilliant. I love them all but the first one is just amaze.

I have only seen the first three and out of them - I like the first one the best. It was something new and exciting in horror films and I can still remember the night I first seen it... Didnt sleep much. lol
