Query: Low on character development

A portrait photographer and a dermatologist/internet sex enthusiast. A failed novelist and a stripper. Closer is about the interactions between these two couples - their infidelities, their fights, their loves.Despite a talented cast, the characters are so thoroughly unlikable (the men crude and boorish, the women weak and forgiving) that I couldn't force myself to be interested in who might be cheating on whom. Their switches back and forth seem to go on endlessly, leaving a viewer begging for release with an end.
