This is not a film occurring in an alternate or imaginary reality; rather, it is a film of NO reality, that is, a picture that changes the rules of its universe strictly according to its creators' whims.

Aimed squarely at family audiences, the Wachowski Brothers' return behind the camera for the first time since the "Matrix" trilogy is a blur of video action painting and very loud sounds notable solely for its technical wizardry. In every other respect, it's pure cotton candy -- entirely non-nutritious but too sweet and pretty for young people to resist.

Unlike a Pixar cartoon that embraces as wide an audience as possible, Speed Racer proudly denies entry into its ultra-bright world to all but gamers, fanboys and anime enthusiasts. Story and character are tossed aside to focus obsessively on PG-rated action and milk-guzzling heroes.

It'll split the ranks like a pizza cutter: you might admire it as a Warholian blur of pop art, gawp and gasp at its Hot Wheels-for-real dynamism, or get a headache.

Young boys are the only suitable audience for Speed Racer, the elaborate live-action adaptation written and directed by "Matrix" creators Larry and Andy Wachowski. And even they might feel an urge to squirm.
