It's strictly fanbait plain and simple, but oddly respectful with it.
The makers of the gleefully vulgar animated series have done much more than glue two and a bit of their half-hour shows together to make a movie andget their diminishing number of followers to the box office.
No, freed of the small-screen propriety they've already wiped their feet on, the team of Stone and Parker sure have gone all out in the tastelessness department.
But at least they do it while making some clever points about how on-screen offensiveness gets the blame for corrupting young minds (the very ones who won't be seeing this, thanks to the high-end censorship rating).
And along the way they throw in disgustingly funny show tunes at regular intervals (where once there were commercial breaks), take random pot-shots at a hit-list of celebrities and a North American land war, and have as a subplot Satan's relationship problems with his demanding lover - Saddam Hussein.
It all starts when the South Park gang - Stan, Kyle, Cartman and Kenny - go see the R-Rated Asses of Fire, which stars the show's cartoon-within-a-cartoon flatulent and foul-mouthed Canadian characters, Terrence and Phillip.
When the boys start cussing under the influence of the movie, their parents are soon up in arms, arresting the stars from north of the border, putting chips in their kids that zap them when they swear and eventually declaring war on Canada.
Yes, Kenny dies early on, but when he's not acting as counsellor to Satan down in hell, he's trying to warn of the impending apocalypse. And in one scene we even get to see what the perma-hooded little fella looks like ... er big eyes, round head, hair ... who would have guessed?
No, South Park's flat animation style doesn't gain much from its shift to the big screen - apart from those songs.
While a weariness to its frantic efforts starts to creep in after the fab first half-hour, the giggles keep coming. Though the ones Parker and Stone try to generate out of needless misogyny and homophobia just ruin a little of the fun.
Hey, but Canada bombs Hollywood's Baldwin brothers, and Bill Gates doesn't survive his cameo either. So it can't be all bad can it?
