I enjoyed most of this film. The first three quarters was good. I found it quite easy to guess who was the bad guy quite early on, but enjoyed watching how everything played out. I like the third party approach that they took to show the serial killers' view of the situation. I have to say I was very disappointed with everything following the climax of the film though. It was like they had no idea of how to end the film. Everything after this point felt tacked on. The adult characters explanation to Simon at the end about how everything happened felt forced. I think this could have been dealt with better through more flash backs of how it happened and allowing the viewer to making the connection instead of just spelling it out. The death of Simon at the end felt boring, like I'd seen this kind of ending a thousand times before.
