The ending was a little too convenient...spoiler
Okay, so it's a pretty convoluted story that they try to wrap up neatly, but one thing is abundantly clear...the last girl standing (who was a knockout) was the one responsible for this mess so why did the kid pull the pin and do her job for her? In his condition would he really care if the video got out? Wouldnt he be more interested in scar face exacting some more payback?
Obviously he wanted revenge against all four of the kids since he was able to communicate after a fashion and had the video set up so he could watch the events unfold. Obviously he should have known that at some point the video would get disclosed as his motivation for hanging himself...so what then? I guess we're supposed to believe that his desire to keep the video from getting out was stronger than his desire for revenge and since he brother saw it he had to die to?
An entertaining enough movie that I enjoyed, just not very logical in how it ended.
