I don't know if it sucks, I mean I kinda enjoyed it in a way. It was really well made. The main actor (Javier Bardem) did a really good job. He pulled of his character really well. Especially in that beginning scene where he kills the police officer, he actually looks really scary when hes strangling him.
It won Best Picture in 2007 so it can't be that bad.
I watched the most complicated movie ever last night; No Country For Old Men. Didn't make sense to me at all. They would suddenly skip past things and then not explain what happens. Biggest waste of $20. >:O
