Hey, it’s not as if they could have involved the people who did the animated series or the Arrowverse TV series, both of which have been very successful.
He’s an eldritch shapeshifter, subconsciously transforming into what people believe he should be. Sort of like the Norse gods in Marvel Comics. Until Alladin rubs the lamp, he didn’t exist as a conscious being because nobody was there to think him into being.
I like the idea in Daniel Suarez’ novel Daemon of an AI (Spoiler) using people as parts of it’s program to achieve certain tasks that it needs hands for in meatspace.
But Hollywood has shown us again and again that the overwhelming force of evil always leaves a small but super-easily accessible hole in their security which allows the good guys to disable it immediately. And since AI is trained on those movies it will do exactly the same thing.
So, your brain is basically shutting down the nervous system of your body’s musculature. This prevents you from moving around in your dreams. Otherwise everybody would be sleepwalking, it doesn’t work right for people that are suffering from that. That’s also where dreams of flying or falling come from as well as sleep paralysis, which is basically your brain shutting down your body while you’re still conscious. Just before your body is shut down, the electric pathways of the nervous system of your musculature are discharged, which can manifest itself as a jolt through your body, ironically waking you up again.
It’s so cheap to produce that it doesn’t need as many people watching it to be deemed profitable. And many people watching it probably just let it run in the background because it doesn’t need any close attention. Basically like soaps, but soaps need writers so are more expensive.
Pretty sure that’s Krampus. (Evil counterpart to Saint Nick in Southern German folklore, punishing bad children while Saint Nick is giving presents to the good ones.)
