Anyone who reviews this movie and was surprised by the vulgarity wasn't paying attention to what they were going to.
It's over the top, but its the subtle moments that are the funniest, like his interview with the model, or with the celebrity charity people.
This movie rips celebrity culture, talk shows, fashion, fame, and Hollywood in addition to just homophobia. People just get distracted by the homosexuality bit and think that's all there was to it.
