I think the challenge and "game aspect" of Top Chef has a great draw on many of the contestants. We as Chefs and Cooks are competitive by nature. The fact that they have other responsibilities, and obligations Im sure has been taken into account before they make the decission to go on the show. As far as being shown in a "bad light", if they go on and act as themselves and stick to that creedo then I suppose that it doesn't matter what other people think. These are mostly established professionals that are already know in the industry in one way, shape, or form and the appearance will only effect them by getting their name out even more. Weather good or Bad.
