I never really understood these kinds of films. What we have here are a group of people attracted to one another, and going through the throws of success, sex and life in some kind of hapless social foray. One that really doesn't produce any kind of result. No happy endings here, and for all of the attempt at humor, there isn't too much that's funny here.
In this sense it's sort of an old fashioned comedy; i.e. stuff that's not really funny to begin with, but is presented with a kind of humorous attitude. Beyond that, there isn't too much to be made of this film.
Mariel Hemingway is gorgeous as ever, and Colin Firth attempts to save a struggling film with superior thesping. The others hold their own in the acting department. Camera angles are fairly plain. There's nothing really inspiring about this film. It promised to be a sex comedy, but doesn't do much for either promise.
Watch at your own risk.
