Query: Great Idea, Abysmal Implementation

The writer came up with a great idea for a mockumentary: Let's "study" the life of an obese human being through the cynical lens of a sarcastic scientitic study and show how this morbidly obese individual got into such a grotesque state. So I jumped on the chance to buy this DVD, thinking it was a complement to the wonderful Super Size Me. Sadly, though, the writer focuses on obvious, scatalogical, and predictable jokes. The DVD grows tiring after ten minutes or so. The production values are more crude and amateurish than a third grader working with his outdated multi-media computer. I own over a hundred DVDs and this one could very well be the worse one I've ever bought.
