An excellent film: Better Luck Tomorrow. A typical coming-of-age high school teen flick, except this one - unlike everything to come out of Hollywood in the past decade - is actually really good. The characters are fairly stereotypical, but for once I'm okay with that. I knew guys like this in high school, everyone did. Sometimes, stereotypes exist for a reason. But the real power comes from how you're drawn into the world of the main character, however outlandish his situation might seem to most of us.
Also, I really dig the fact that there was no nice and tidy wrap-up at the end. Plenty of issues are left unresolved, and we are allowed to imagine for ourselves how things will turn out for our protagonists. It was a breath of cinematic fresh aire.
