“Bandersnatch” offers an unusual television experience — but not a very satisfying one.

The new “Black Mirror” special follows Stefan Butler as he attempts to turn a science fiction novel (also called “Bandersnatch”) into a Choose Your Own Adventure-style video game. As the story progresses, Stefan gets pulled deeper into the mystery of what happened to “Bandersnatch” author Jerome F. Davies, a mystery that eventually involves parallel universes, government conspiracies and Stefan’s own family tragedy.
