I will say this, I love these types of thrillers were the fun comes in trying to solve the mystery before it's revealed. I did have pretty much all of it figured out half way through the movie. Well, as much as I could "write it" in my head. The only reason why I was off in some places was due to the plot holes, i.e. the screenwriter failed to fill in said holes, which I did myself anyway. So, suck it screenwriter that didn't do his job!
