If sadistic torture and a constant barrage of brutality is your favorite flavor of horror, The Collector will be right up your alley. More than any Saw movie could have done, though, it proved to me that this kind of stuff really isn't my thing.
There's a story here, but it's just a setup for about two hours of people having horrific things done to them. I'm not squemish about violence, blood, etc., but at there's a certain level where there's no entertainment in it for me. The Collector crossed that point at about the thirty minute mark and never looked back.
I'm not saying this is a bad movie, my score is simply an indication of the fact that this is so far removed from the kind of movie I like, that I found it to be unbearable. Hopefully I'll never see anything like this again.
