This was yesterday, but I found out there was a British children's stop-motion animation program called Tottie: The Story of a Doll's House. And it's... dark.
*contains spoilers*
It's based off a book written in 1947. It's about a small, cheap wooden doll named Tottie who is over 100 years old, and her motley crew doll family, such as Mr. Plantaganet, who was once a traditional Scottish doll in Highland clothing, but the children who once owned him ripped off his clothes and let their puppy chew up his leg. He now acts very timid and probably has PTSD from the abuse, not unlike the WWII soldiers during the time the author wrote the story. His wife, he mostly just sits around, reading his newspaper and worrying a lot. His wife, Birdie, is a cheap celluloid doll that was found in a Christmas cracker, and she seems to have intellectual disabilities or a mental disorder of some kind. She's nearly always happy and singing, but she's pretty annoying. And they have a son named Apple, who is a small plush toddler doll who is also pretty annoying and likes to fall down stairs. And a toy dog who is also annoying. The dolls later get a dollhouse to live that happens to be the same one Tottie lived in many years ago, but they have to share it with a rude and nasty china doll named Marchpane, and then she lights up one of the dollhouse lamps and puts Apple in danger. In spite of her fear of fire, Birdie runs into the room and saves Apple, but being made of celluloid she burns up immediately. The two girls decided they didn't like Marchpane so they sent her to a museum. You'd think being locked up in a museum where kids aren't allowed to play with her would be karma for Marchpane, but she didn't mind it at all. She enjoyed being admired without being touched, and it only made her more narcissistic. Meanwhile Tottie and the other dolls seemed only to be sad about the death of Birdie for a very short time, if at all, and Tottie even admitted Birdie looked beautiful in the flame.
Yeah, I saw a video about the show where it was basically ripped apart by the YouTuber, and even though it seemed somewhat like dark and edgy version of Toy Story, it apparently was very slow and boring when it wasn't being disturbing. And there's a second series of the show, which I'm hoping I'll be able to check out soon.
