Personally, I find him to be a bloated bald bumpkin. His show appeals to the Wal-Mart crowd: undereducated, underemployed, cigarette smoking, pepsi-drinking, overweight, bored women in search of quick answers to their multitude of problems. Okay, he's an entertainer, but what irks me about him is that he comes off like a know-it-all on every topic. It's like positivepsych said, Dr. Phil is not only peddling his lame show, but he's selling books on weight loss (sorry folks, the man, while not obese, is NOT thin!!!), nutrition, and even healthy cooking (from Texas?). WTF? Not only that, but his 26-year-old son is an expert on adolescents and their problems and goes around giving talks to high school and middle school students about peer pressure, etc. Phil's son isn't a psychologist or social worker, but comes off like an expert like daddy does.
He is just puffery. I've seen a few of his shows and his advice is the type of advice you'd expect from a parent, co-worker, friend, or significant other: basic common sense. His advice, however, is completely devoid of therapeutic substance.
