So if you dont like XXX buy the regular collection and turn off the one or two xxx scenes.
Some xxx cards are still good value, even when you turn off the xxx bit. For example I have Angelika Greys xxx cards with 15mins turned off and the result is a great striptease.
The issue is that until we buy an xxx card, we don't know whether we're going to get 20+mins of xxx and a bit of perfunctory tease or we're going to get a little xxx and a lot of dancing. Whatever your preference, you need to know roughly what you're buying. The comments and ratings often reflect the disappointment that many people feel.
Totem could adjust the rating system, as
@HansSachs suggested, or give prospective buyers access to the clip-list. Either would reduce disappointment and probably increase sales of xxx cards.
