Portnoy's Complaint

I usually dislike movies based on famous novels. This one is funny, bold and deep, yet the critics think it's trash. My criticism of the movie is that it didn't go far enough. Richard Benjamin is terribly miscast. He is far too handsome, patrician and cool. He belongs in a country club, hunting foxes. They should have picked a homelier, less serene type. The action should have been less restrained and "tasteful". They should have laid it on thick, used more camp. At times the film looked like a Ross Hunter production!!! It was too nice and smooth. But despite these major insufficiencies, it is one of the better films ever made. I must read the novel. But how can I do that, given my vow never to read fiction again?
