These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Nausea Fuel: The only purpose of this film. THE ONLY PURPOSE.
So Bad, It's Good: Considering how the marketing seems to BRAG about the bad reviews, this seems to be what Waters was going for....
Squick: Possibly the greatest concentration of squick in the history of cinema.
Tear Jerker: Yes, of all films! Admittedly, Divine's reaction to seeing her trailer, her home, burning, was quite the whiplash. She dropped to her knees, crying uncontrollably. Even in a World of Ham movie like this, the way she acted was still pretty damn convincing. Worse, after they vowed that the criminals will not make it out alive and leave, the scene ends with the shot of the trailer collapsing, literally burning down to the ground.
Values Dissonance: The Marbles are guilty of much evil, but many modern viewers probably aren't bothered that they adopt out babies to lesbian couples.
Seeing that the adoptive lesbians parents seem to be the most decent and grounded characters in the film, Waters may have been making a point about how ridiculous it would be to consider them inappropriate parents. Keep in mind, Waters and several other members of the cast and crew were homosexual or at least bisexual.
Keep in mind that the babies were conceived via abduction and rape. Also, the payments from the lesbian couples is used by the Marbles to finance heroin dealers who target inner-city elementary schools.
