I was more interested in the killer's past than everything else in the plot. the problem is, i've seen this kind of storyline before and i wasn't impressed. the torture scenes are good!

I don't understand how anyone can compare this move to Saw. In what way are they alike?

What we see is a group of pre-teens bullying an outsider. Because of their actions, the bullied boy is kidnapped and lives a horrible abused life. The thought that this child could could, 20 years later, track down a group of kids he knew only briefly is ridiculous. He didn't know their names or where they were from. He knew nothing about them. After they brutalized him, he was kept captive and had no contact with the outside world. He was completely isolated. How would he find them, much less take them hostage? I'm fine with suspending disbelief but this is too much. This is just a dumb movie with a bad script that makes no sense. Of course there's also the "hey, I forgot all about that kid I terrorized that one summer. I guess I do know all of you" reveal. Was that supposed to be a plot twist?

Don't waste your time watching.
