This movie is actually really influential to an entire subgenre of videos about high scores and speedrunning on Youtube. This is also a touching and real movie that doesn't ever really get wrapped up in much judgement of its own.
I get it. Why everyone's chanting and cheering. It's because the man directing this would later go on to direct such classics as The Social Network and Fight Club. You know I'd be screaming too if I knew that while I was at this terrible concert!
