Kid Sparkle, porn's least ingratiating youth-market auteur, comes to DVD with the release of Party Girls. For all his personal, intensely unlikable qualities. Party Girls is a good gonzo vid, and parts of the DVD reflect that. Other parts are grainy, pixelated, and have more video artifacts than an Atari 2600 game. If Leisure Time hopes to be a force in the DVD market, they have some MPEG-2 homework to do.
