When I started watching this movie I was really concerned that it would be pretty mediocre, unimaginative and dull, having lost my confidence in teen movies with the disintegrating ending to American Pie 2. But this is great and I'd recommend it to anyone who doesn't want to fuss around with movies and wants to watch a winningly no-excuses, riotous and unapologetically immature American comedy. The storyline is pretty formulaic (a teenage rollercoaster term at a high school in nowheresville America ending in the climax of the national institution of the prom), but you don't really notice it with another clever gag always around the corner. With American teen stereotypes to the fore, it bluntly sends each and every one of them up without nerve; the demonic geek; the issues-heavy cheerleader; the over-confident jock; and my personal facourite, the ethnic stereotypes - the black character's role a cheeky pop at colour-conscious America. Its winning element though, is its insistence to be unapologetically sick and vulgar with its humour, especially a particularly disgusting collapsing toilet scene, and the blatant incest gags, and there's also a strong element of very un-American irony throughout the film - the quirky spoofs of Grease's most cringeworthy moments, and even in the title.
One of the best films ever to switch your brain off for - and I mean that in a nice way.
