A pair of engineers create a mysterious machine that at first they are not sure what it is, but once they understand it they know they have something special, but become consumed with it and are not able to scale themselves back.
An original take on that age-old notion of time travel. This is one you will have to watch more than once (maybe with the commentary too) before you'll understand what's going on. Still, for a low budget is has high impact.
This one is one of the most original movies of 2004, if not of this decade. It is a little bit too confusing the first time, and maybe a second time could clear some things up. I can't say much, other than if you love sci-fi - see it!
