If you ever want a movie that will screw with your brain, this is it. And I don't mean screw with your brain in that 'whooa man, I bet this would be great on acid' kinda way, I mean screw with your brain in a 'what the hell is happening and does this even make sense?' kinda way. The story involves these guys building a machine that can take them back in time by generating a kind of loop that begins when the machine is turned on... and gets more and more complicated until finally you're sure it makes sense but you honestly haven't any clue as to why or how. If you're a genius, you should watch it... and then tell me what happened, because I have no idea.
