I've become kind of a fan of the "filthy but surprisingly still upholds traditional values" comedy genre, exemplified by The 40 Year Old Virgin and Knocked Up. This movie has some of that cinematic DNA, but didn't work as well for me.
Three high school seniors are looking forward to an evening of liquor-fueled debauchery, since they've been invited to a party, and they're the kind of kids who rarely get invited to parties. Only problem is: they are tasked with obtaining the alcohol. This turns into a peril-filled odyssey involving two of the worst policemen in America, bums, bad drivers, liquor store robbers, etc.
The "lesson", such as it is, is that drunken party sex isn't all it's cracked up to be.
OK, it's pretty funny.
But one big problem is that the movies I mentioned liking above have explicitly adult characters. The high school characters here—they probably hit a little too close to home for someone with kids only slightly older. I know, that's just me. But still, when I read on the IMDB trivia page:
Because (Christopher Mintz-Plasse) was only 17 at the time of filming, his mother was required to be on set during the filming of his sex scene.I'm a little: ewwwwww!
Another problem: one of the characters never seems to get his needle off the "pathetic and irritatingly obnoxious" peg.
