I'll be honest: I didn't understand the whole movie. I was slightly confused for the first 60 to 70%, but then I got really lost and gave up trying to follow it. This time-travelling B-movie really captures the complexities of time travel and doing so leaves the viewer wishing they had a Coles' notes of some sort. To be fair, they did deliberatly make it confusing with the voice over and constant jumping around, especially at the climax of a scene. And these guys talk like two of the nerdiest people you would ever meet.

If you want to follow this, better brush up on your physics and mathematics, especially the parts about recursion. Very intelligent movie, no doubt. Either these guys were Physics majors or they did a lot of reading, because the subjects of their near-constant discussions was lightyears above the standard fare seen in other movies. It was pretty cool to see all the minute details involved in the creation of the machine.

Still, it was enjoyable despite the odds. No romance or action, an impossible to follow plot and B-movie quality (it cost $7,000) make this not for everybody. Think of the movie "Pi" without the psychology.
