The Thanksgiving episode was pretty cool. I especially loved the segment with AI Marge. I think it might be more enjoyable if you can pick out the Black Mirror references.
The main plot centered around the dark horror of "White Christmas" which includes at one point a man being trapped, immortal, in a cabin for at least 1.4 million years. Marge was what they call in show "a cookie" and people have no moral qualms about trapping a being that is for all intents and purposes a human, in a dull void for huge stretches of time. This is a common theme on Black Mirror.
Marge getting downvoted at the end of a segment was a reference to "Nosedive".
Maggie had a Waldo doll from "The Waldo Moment".
AI Marge's plan to escape to the Internet was from "USS Calister".
I think Moleman getting hit by the pizza truck was also a reference, but I forget the episode. I think it was that one with the insurance agent in the world where a machine can read peoples' memories.
Something had the strange glyph from "Bandersnatch" and "White Bear"
Any other references I missed?
