Primer

Normally if someone told me they wanted to watch a sci-fi movie about time travel that had a budget of 7,000 dollars I would expect them to be describing some terrible made for sci-fi channel movie (this means it is worse than normal made for TV movies) that has script that seems to have been written by someone who just started to learn English as a second language. However, in the case of Primer 7,000 dollars gets you an intelligent script that uses language that for most intents and purposes is scientifically correct. This is combined with a story line that keeps you guessing, plot twists that are guaranteed to throw you for a loop, and some surprisingly good acting for a bunch of unknown actors. Primer has also developed quite the dedicated cult following, who have generated graphical time lines and a 20 page paper to fully explain the story.
