I had been asked to review this when it came out but didn't. I'd review it now, but I don't remember it, except that it was pretty damn funny. As polynikes and someone noted, it's Ace of Spades HQ Lifestyle compliant, which means it has jokes about Live Action Role Playing (D&D's even dorkier cousin), KISS, pederasty, and tits. There's even a stray hobo joke. (Not a hobo hunting joke, though, as some people erroneously heard it.)
It comes out on DVD on March 10th.
The trailer doesn't really give away the better jokes, which is welcome, but it also undersells the movie.
It's R-rated and it earns it. Not to the extent that My Best Friend's Girl does, but it's not a family-friendly comedy, despite a premise that might suggest that.
