To those who say Carl wasn't good-looking enough ...
To those who say Carl was to fat, ugly, etc. to realisitcally be with Inez and Molly.
You are all dead wrong.
(Not that sheer looks should determine the way audiences interpret the story of a film. Characters' looks, when used properly as I feel this film does, should be utilized to convey the characters' feeling and attitudes, i.e. evoking pathos; this means if you are uncomfortable with Carl's looks, and don't buy into his ability to couple with hot women, this does the story service because it reflects the way Carl feels about himself and his virility as a man. But I digress.)
I worked in the restaurant business for many years. Worked with a sous chef for several years that was a lot like Carl, but not as good looking and even more overweight. This sous chef's wife was even better looking than Inez. And he had women better looking than Molly falling all over him.
True story.
Culinary prowess trumps good looks in many women's eyes.
