I wonder which one is the director's cut. I did not see either version before last night. Anyway, I though it was good entertainment with some thinking behind it. When it started it quoted something from either "Quantum theory" or "Chaotic theory" both of which I have come across some how. This is one of those movies that while you are watching it, you wouldn't know in what timeframe you are watching. What I mean is that the movie stars in the past of the psychology student. It is not understood until later (very late) in the movie that this is what is happening. Various outcomes are portrayed when various choices are made. Umm... This is something which definitely is something that I agree. The choices one makes today will have consequences tomorrow. Some which we will see and some which will not even know that happened and how it affected those around us. Good movie.
