Great things should be spread. Maybe you're in Africa and can't take even a single DVD with you but can get internet access. Maybe you're chatting online and want to show a friend one single magical movie that explains why you're not an idiot for liking kung fu films and you can send them this link in a few clicks with no time or money investment from them and oh shit it's magical. Maybe someone who likes movies but gives 0 shits about video quality wouldn't end up seeing this film any other way. Maybe someone on YouTube will browse to it by accident and discover it.
