If you honestly think all drunks are the same, you've never really studied human behavior. Yes, at some point, drunken behavior is predictable, but this film isn't merely about that.
Also, keep in mind that context is important for almost everything. The context here is documenting a very un-documented section of American culture in 1986. Yes, this kind of music was all over MTV at the time, but no one really dove in deep enough to the fanbase until Krulik did here. This film is not merely about drinking, partying and watching a cheese rock show. If you think that, you should stick to whatever it is that you feel comfortable watching.
It's also not easy to waltz into this kind of crowd with a video camera (again, in 1986) and be accepted. These "metal heads" are normally prone to kicking the krap outta people. Krulik does this with ease and gets them all hamming it up and posing for the camera as if he were one of them.
This film puts you there, makes you want to have a beer and sink into an aspect of culture you might not know or feel comfortable with. THAT is something!
