Ron, I'd say Waters' early films (Multiple Maniacs, Female Trouble, Pink Flamingos) are more than just a bit bizarre, LOL. I've shown PF to several friends and they've probably been psychologically scarred by it. While it has a lot of the darkest comedy imaginable, it also has plenty of content to disgust and outrage anyone who watches it. It's a difficult film to defend, that's for sure.
Waters has certainly produced some iconic film images: The Cha-Cha heels/Christmas tree scene in Female Trouble; the doggy doo-doo-eating scene in Pink Flamingos (actually not the most disturbing scene in that film by a long shot); Divine being sexually assaulted by a 15-ft. lobster in Multiple Maniacs (again, far from the most disturbing scene in the film). Everyone who's seen his movies has their favorite lines to recite.
