This movie was pointless. I can't enjoy a movie if the characters only make completely ridiculous, illogical decisions. That's all that happens in this movie. One terrible decision after the other.

[spoiler] The dad's reaction at the beginning was so damn stupid. There were no real reasons why he didn't call the police. They could easily just have said the girl fell, nobody saw what happened! Everything just got more ridiculous from there. And I do NOT buy that any teenager would be so stupid that they wouldn't realise "oh wow my dad fought with my friend's dad, and now my friend's dad is CHASING ME IN HIS CAR, and also the police is involved, maybe this has gone too far and I should tell my parents!". No. Nope. It makes no sense. And the parents' behaviour... I get that it's supposed to be like "parents would do anything to protect their child" but even then it doesn't make any sense. And it just made them seem like awful people, not great parents.[/spoiler]

Also, the twist was obvious way before it happened. And it did not make anything better. The whole set-up in the beginning was so terrible that nothing could make it better.
