this movie wasn't sure what it was. for a "feature" it mostly long and boring. for a "couples" it was predicable, modestly acted, and some of the sex (my wife isn't into anal) was a bit too hard core, and even then it was hard to feel "into" the sex. it was, for the most part, sex for sex.
and the sex was broken up with long bouts of bad bad lip synched musical shots. not bad, but not that good either.
