After reading many reviews, i finally decided to see how bad it was for my self. Surprisingly it wasn't as horrible as i thought i was going to be - dont get me wrong, the concept and killings are ethically horrible. But It wasn't as disturbing as i thought it was going to be, during each of the killings the FBI is watching, so it isnt pure torture just watching the actual killing, cause all of the FBI agents and everyone are working on it - making it seem less intense and disturbing. There wasnt really any gore at all, gore suggests that you see the insides of people and guts - none of that was shown. And the "disturbing" scenes dont fully reflect what they would look like in real life so it isnt really hard to watch. I wasn't really scared at all - I hate horror movies, yet i wasnt scared at all by this fyi. If you watch many movies, game a lot, and aren't too new to crime movies - this movie should be perfectly fine for you.
