Remember Dr. Leo Marvin, the egotistical psychiatrist in What About Bob?, who was more concerned with promoting his new book than in helping his clients? How about Lisa Kudrow’s self-absorbed Fiona Wallace in Web Therapy, who conceived of a new “modality” of therapy that replaces the traditional 50-minute session with 3-minute sessions delivered via Webcam? These characters were so obviously caricatures that no one would confuse them with their real-life counterparts. But even more subtle screen portrayals of therapists can be misleading, since they’re primarily designed to create compelling drama than to provide a realistic depiction of therapy.
