Even knowing the story behind the movie I was still taken aback. The performances were solid, and the ending made my gasp out loud. Seeing the story play out gave me such a different perspective and understanding of the absolute lunacy we humans can go through.

Really engrossing movie. I was totally captivated by the characters / performances of Jonah Hill and James Franco. The use of extreme close-ups was very effective

Not as suspenseful as I expected but interesting story, and extremely well acted.

Great movie, as it keeps you guessing till the end.
