A few years back, I watched a documentary about a pair of Swedish brothers whose parents had home through a bitter divorce when they were younger; the mother had become obsessed with trying to wrest away a vacation property that she and her husband had owned that her life became focused on this legal case to the exclusion of almost everything else in her life. it seems. She became a hoarder, living a hermit-like existence, and eventually stopped communicating with her sons. They eventually made their way to her apartment to check on her only to find she had died, and laid on the bathroom floor for so long she had mummified, and when they picked her up found this indelible stain on the bathroom tiles they tried to clean fruitlessly. They also had to sort through mounds of paper, legal documents, etc., and although the landlord asked them not to, they burned copious amounts of her papers in the fireplace. I don't know if this movie actually fits the parameters of kinder trauma, but it was pretty disturbing when I watched it a while ago, and your readers seem pretty good at coming up with answers for this kind of thing, so if anybody remembers this film, I'd appreciate the help. Thanks!
I think this might be what you're looking for? The English title is Seven Dumpsters and a Corpse.
