Woah

Primer is a fun movie which combines the mind-bending plot of Memento with the realistic style of a Chuck and Buck. The story is about discovering the ability to travel time. Two friends are using their spare time to experiment in their garage. Their approach is to find something new and then look for an application. They stumble upon the ability to move briefly backward in time, which they of course use to make money. When they start trying other things, the multiple timelines will start to spin your head. I'm not really sure what happened in the last third of the movie, but it was fun to watch.

The movie was shot for less money that a good used car, but it doesn't really show. It looks quite good and most of the action consists of conversations between the two experimenters. You have to pay close attention to apparently insignificant conversations as major plot developments are often mumbled or thrown in as an aside. There is for example a bad event the heroes try to prevent, and you could easily miss the point at which they discover it will happen.

This is certainly one of the more entertaining ones of the genre I have seen.
