It was amazing. I've seen it three times and its still just as good as the first time (with the element of surprise taken away, of course). I honestly thought it was going to be a flop, or have a *stupid* plot line/ending like Shutter Island; add to that the misleading poster about "Your mind is the scene of the crime," and you get the idea of a crime thriller. But I was pleasantly surprised; ah, well, blown away actually. This is one I'll be waiting in line for on Blu-Ray.
