The premise is odd, and so are the results. Herbie tries out options like Crime, Government, and Health Care, none of which encompasses anything close to what he thought it might. He even toils with a few romances in the process. The results are inspiring as often as they are funny, and that's most of the time. I especially liked The Big Red Chicken.
Nobody can deny the significant amount of symbolism either.
Some are confronted on a larger scale than others, but the book makes its points loud and clear. It's mostly little things that take away from the book. In fact, you don't have to look far to find criticism on some things. The book itself says that using too many parantheses can be distracting and annoying. Those are all small nuisances, though.
