Metacritic reviews

A deliciously amusing socio-culinary prank.

Hilarious and often terrifying look at the effects of fast food on the human body.

It’s one of the blackest comedies to hit the screen since Dr. Strangelove. Spurlock proves himself a supersize talent; he makes you choke on every laugh.

The movie is zippy, laugh-out-loud funny, persuasive and at times horrifying, as Spurlock undergoes his unpleasant changes with good humor and bad tummy aches.

Sometimes exerts the gross-out fascination of reality TV's muckier specimens--its arc suggests a slow-motion "Fear Factor," or "Extreme Makeover" in reverse.

Spurlock's film proves yet again that the phrase "crowd-pleasing documentary" doesn't have to be an oxymoron.

The speed with which a healthy, relatively young stud can morph into a tub of lard is as horrifying as it is entertaining to watch.

The results are as entertaining as they are sobering.

Primarily humorous in a believe-it-or-not fashion.

Spurlock's movie is an attack on our eating habits, but it's also a prime example of an all-American sport--making a spectacle of oneself for fun and profit. Spurlock, you'll be surprised to learn, is developing a TV spinoff, with himself as host.
