OK The title doesn't really help - Slutty sounds like a soft porn type film, which it isn't. This is an obviously gay, very lightweight, but very enjoyable film. The characters are over-the-top, yet I could recognise traits in friends of mine and it is easy to sympathise with them as the story evolves. Eventually, it all comes together and you realize that there are true emotions in there as well as all the camp and bitchiness.
There aren't that many good, enjoyable gay films around. "Mambo Italiano" comes to mind. This is at least as good. Give it a try, I'm glad I did.
