text: A sexually obsessed chef leads a duplicitous life: one as a "happily" married man with a ten year oldish child, the other as a sex fiend. The bulk of the documentary-like film follows him for five consecutive days and is told in flashback with Nastassja Kinski as a clinical sex therapist, listening to his story and intelligently probing him. Nastassja's role is very restrictive and she is the only principal adult character who does not take off her clothes. If she had, I would have rated this movie a big fat "F." As it is, it rates an F+, implying that it is still a failure unless one likes to be bored. It is probably a lot more interesting to spend ninety minutes cleaning out the garage. "Diary of a Sex Addict" falls into the category of films that once one has seen it, one wishes that one hadn't.
