just watched this film. saw a lot of derision on here for it so had to comment. this film asks some really good questions and doesn't ask a lot of other questions. This film lets the viewer think. A quality that so few films allow these days. Yes, there is a formula to this film but that is not a bad thing. The themes this film allows you to think about need a familiar plot point to ground it so we as an audience can relate. Sure this film is not Oscar worthy if that matters, but that doesn't make it a bad movie. This film reminds me of the 'Lifeboat' exercise I did in drama school. The 3rd solution to the puzzle made so much sense to me. Watch it and make up your own mind.
