Primer is probably my all-time favorite. I'm in love with the whole thing. The story, the acting, the soundtrack, all phenomenal for what is basically the work of one guy.
The best part, though, is the feeling that you could go out to your garage and build something amazing.
yes! this was a big deal to me when it came out. I don't know why more people didn't go for this type of indie sci-fi type films. If you consider it sci-fi. Regardless, great movie with such a small budget.
