One thing that I admire most about filmmaker/docudramatist Morgan Spurlock is that he tries to convey both sides to his stories. Yes, it's easy to poke fun at McDonald's and it's even easier to look down on the government for its lack of alternative to fossil fuels, but chances are, that you're looking at it from an outsider's perspective.
To make a valid argument, you'll need to understand both sides to an issue. And although he clearly has a point to prove in all of his works (corporate carelessness and consumer ignorance in Supersize Me, the lack of government efforts towards a cleaner, safer and preserved environment as a coal miner in 30 Days) he also makes sincere efforts to understand the opposition's viewpoint by immersing himself inside the issue rather than above it.
Until you put yourself in someone else's shoes, you'll never fully understand why things are the way they are. Even if it is just for 30 Days. That's 30 days more than you and I have put in.
