The mainstream reviews will be all OMG JUDD APATOW PLEASE LET US BE YOUR LOVE SLAVES YOU ARE SO AMAZING. Entertainment Weekly will probably have an ALL JUDD APATOW issue... which will differ from its normal issues in name only.
A few feminist critics will be like RAGE RAGE RAGE SEXIST MISOGYNISTIC PATRIARCHY HEGEMONY RAGE RAGE RAGE ARRRRGGHHHH.
And everyone will ignore the fact that the movie is probably stupid and not all that funny, a la Freaks and Geeks and The 40-Year-Old Virgin (I've decided I officially like Knocked Up). That said, the "Were you mad when you died at the end of Die Hard?" line that they keep playing in the trailer is really funny, but nothing else in the trailer is. And when the trailer, which always has about 85% of the funniest lines in the movie, isn't funny........
