What happens when you eat McDonald's for thirty days, three meals a day, super-sized when asked, widely sampling selections from the entire menu from Big Macs meals to yogurt parfaits, salads and fish filets? With a team of highly qualified doctors monitoring his health every step of the way, director Morgan Spurlock answers this question: your body falls apart.

Spurlock also has the perfect narrative hook: himself. Following in the tradition of Michael Moore, Spurlock is the narrative hero of his own film and this is just fine. An articulate speaker, he is also a compassionate listener and a wonderful guide.

Over the course of his experiment, Spurlock gained eighteen pounds, became depressed and withdrawn, suffered from severe headaches, mood swings and disturbing chest palpitations. All of these shocking changes take place on camera. After thirty days, he goes into liver failure.

"Super Size Me" is a terrific film that takes the seemingly not-so-sexy subjects of health, nutrition, and corporate greed and turns them into informative entertainment. Crisply edited, Spurlock's steady stream of meals at McDonalds are cut with interviews with his vegan chef girlfriend, his concerned nutritionists and doctors, fast food consumers, and corporate lobbyists.
