Not much sex
20 April 2003 | by (Canada) – See all my reviews

For a movie titled so provocatively it sure had very little sex or nudity in it. The plot is your typical 90's lame pop culture brain rot. The writer/director is an ignorant and dishonest sell-out. I gave this nugget of nastiness a 1. I suppose one can mention a single good thing about this waste of time: Mariel Hemingway did it during a spell in which she was minus her usual breast implants. Her lack of talent was routine however.
