There is a philosophical component to the plot of the movie. I think that ruined it. Other than that, it started cool, the pace was good, the story was interesting, I was hooked. Then, at about half, the entire thing turned into the old "what is going on? Am I insane or is it real?" cliché which I personally abhor. And then the ending explained some things, but didn't really make me understand why I spent a quarter of a movie watching scenes that didn't make sense. And then it ended with a weak "don't play god" thing.
I really wanted it to be more than a back of a napkin plot twist at the end, but it wasn't. So much setup for something that was basically a butt of a joke. Physics doesn't turn into metaphysics just because you equate apples with oranges.
Bottom line: it started great and it fizzled in the end. The structure of the movie was good and the ending was artistic enough to not really matter in the overall story.
