Ehh... it wasn't that good. The graphics were pretty terrible throughout and the audio was muffled and grainy. I can see the message behind this movie, as I share the same opinion as you on those kinds of reviewers, but this wasn't really the best outlet for your message I think.
The sterotypical portrayal of the guy was pretty funny though. Why was it funny to make him gay though? Surely the kind of person who likes Eminem and hates all kind of stuff they class as boring isn't going to be gay? And just because someone who is reviewing your work hasn't submitted anything themselves, does not make their opinion invalid. It's always good to get feedback from your peers, other flash artists and the like, and their advice would undoubtedly be better than that of random Joe Schmoe, but thats not to say that they too won't have any contructive criticism for you.
