I found the movie to insult my intelligence anywhere possible and while I found Spurlock charming... I found him to be somewhat of a shyster.
It's been a couple of years since I last saw it, but if I recall- the first McDonalds lunch he has causes him to projectile vomit all over the parking lot. I guess maybe the movie should have had a "results not typical" disclaimer on it, like other diet products, because I've had lunch at McDonalds. I've probably had 100 lunches at McDonalds. And never have I, or anyone I've ever seen at a McDonalds, puked like that after lunch.
Maybe if that was his 10th lunch (breakfast, dinner, etc...) there in a row...
I also watched some of his 30 Days show. I saw the "minimum wage" one- I can't remember if I saw any others. It was about as scientific as a Sprite vs 7-Up taste test put on by Sprite where everything is clearly labeled and you get a free 24 pack if you say you prefer Sprite. He set out with an agenda, and he was in full control of the experiment, and- SURPRISE! it proved everything he thought before- no couple could possibly get by with 2 minimum wage incomes.
Despite the fact that lots of families in America get by on 1 or 2 minimum wage incomes.
