I think the films one finds funny is no real indication of anything other than a sense of the type of sense of humor one has. I don't usually find Bill Murray funny in anything. I did not find the plot of this movie or the dialogue or the action funny. It is not my kind of movie in its type of humor - it would not be funny if it were any profession to me. It has nothing to do with the therapy aspect of it to me.
I loved the tv shows Head Case and Web Therapy. I found the therapy scenes in Ally McBeal to be funny. I found the cartoon Dr. Katz to be funny and I really liked the comic strip about a therapist called Go Fish.
