I love What About Bob. Had forgotten about it until you mentioned it.
I consider it a conservative movie. The elitist intellectual is really the crazy one.
Very true, Dreyfuss plays the role of the insufferable uptight Dr. Leo Marvin perfectly and has the liberal mannerisms down pat. As the author of a fluff touchy-feely "self-help" book with the obligatory spot on the morning TV talk show, the doctor apparently gets really annoyed when his patient (Bob) actually takes the content of the book seriously.
The movie does a great job exposing Leo Marvin as the fraud that he is and it turns out that the patient actually has a lot more common sense than the full-of-himself doctor.
