Metacritic reviews

More than ever, Johnny Knoxville and his boys belong to a very elite club of idiocy. They martyr themselves for our diversion, driven at every moment to ask: Are you not entertained?

A joyous, liberated approach to comedy, a genuine sense of the grotesque and pacing so relentless that even the less-than-uproarious bits don't overstay their welcome.

Whether he's getting hit in the face with a dildo or cozying up to Martha Stewart, Knoxville is always affable, playful and able coax a laugh out of an audience by doing ridiculous things. He's a jackass all right, but he's a jackass in shining armor.

Knoxville and his boys seem to be saying goodbye. To which I can't help thinking, fondly, it's time.

The 3-D effects, so promising on paper, don't really add much-and, worse, there's a overreliance on slow-motion, which kills the fun.

While Jackass 3D can never be accused of stinting on its spring-loaded arsenal of projectile bodily fluids, neither does it approach that sublime, laugh-until-it-hurts level of gross-out nirvana that made the first two installments so darned irresistible.

Ten years into the "Jackass" franchise, it's obvious the well is starting to run dry. Then again, if you show Johnny Knoxville an empty well, he'll jump in headfirst. After packing it with writhing snakes.

It just might be that America's favorite jackasses, having played around with sharks in their last big-screen effort ("Jackass Number Two" of course), have this time actually jumped one, and in 3-D no less.

Those Jackasses from "Jackass" aren't getting better, they're getting older.

Oh, and one more thing the comedy of Jackass 3D has in common with "The Divine Comedy": Neither of them is funny.
