The characters are obvious stereotypes - the bitch, the sweet one, etc. If you aren't well acquainted with your companion for the evening, finding out if they sincerely like this movie will help you weed them out without a lot of unnecessary, time-consuming conversation. If your date says he or she likes genuinely likes this movie as a story of a plucky girl trying to make it on her own, you will be relieved of the pressure of trying to make a good impression for the rest of the evening. Order a big dessert, talk politics, criticize the date's taste in music - you won't be seeing that person again. If, on the other hand, you both agree on the movie's badness, you'll have lots to talk about.
Nothing brings two people together like the merciless dissection of sub-par entertainment.
Actually watching the movie won't be too painful for either party involved in the date. For men, there is the obvious attraction of watching well-shaped young women dancing on a bar in skimpy clothing. For women, there is the attractive Australian fellow who drives a spiffy classic car and collects vintage comic books - both of which, for some of us gals, are quite a turn on. Though it could easily be mistaken for mainstream porn, I don't actually remember any nudity. And, there's only one sex scene which doesn't last too long, if you're still at the point in the relationship where on-screen sex is kinda awkward.
