No question about his guilt, but .......
No question that jeff is guilty. Director did try to make it ambiguous so that the plot can survive till the end.
What made this movie pathetic for me is how a 14 yr old was able to plan all that while the homicide is still not solved. Even in the coffee shop we see missing poster still on. All the technology, staff with law enforcement and this teenager beat them all in planning a perfect revenge. Surely this was not a fantasy superhero movie..........but a realistic drama movie. Or did i just watch kick-ass 3. Hayley character surely looks like Hit-Girl character in that movie, hell she even looks like her :)
And if Jeff really was the killer, what problem he has to also kill hayley and his ex with his knife and run off. I just don't buy this crap of overwhelming eternal love for his ex, and still able to do rape and murders. It is so effing unbelievable that it is a little funny.
Still this is not my biggest objection with such movies. What msg is this movie sending out. Be heroes, take revenge, kill. Hell there are enough problems in modern society with these pedophiles out there, I hope this movie does not inspire teenagers to go after dangerous people and get in trouble. I do understand cinematic liberty, but this movie was truly a sorry excuse ......
