Reviewing Jackass 3D isn't only a seemingly pointless exercise--it's a hard one. There's no plot, but that doesn't mean there's no structure; the Jackass movies are built like grandiose symphonies of stupidity. It's what makes them the dumb entertainment that smart people find safe to enjoy. Contrary to their critics, the Jackass films are not evidence of society's slow slouch toward idiocracy--being this fucking moronic requires way too much thought for that to be the case, and director Jeff Tremaine strings these skits together with a cartoon logic that Chuck Jones himself would applaud. There's no way to spoil Jackass, either: The introduction of every skit shows what it's going to do, then it tells you what it's going to do, and then it does it. I can tell you, for example, that Ehren McGhehey has dental floss tied around one of his teeth, and that the other end of that floss is tied to the bumper of Bam Margera's Lamborghini; you can deduce the rest. It's not about knowing what's gonna happen, it's about watching the shit go down. And I haven't seen anything this year funnier than "Poo Cocktail Supreme," "The Field Goal," "Pin the Tail on the Donkey," and about 10 other skits I won't even name. by Bobby Roberts
