Here's how to get the best ending in Black Mirror: Bandersnatch (although that may not actually be a good thing). The Netflix anthology series has always probed our reliance on technology, but this standalone movie takes it to a new level. Bandersnatch is a choose-your-own-adventure story in the spirit of horror and fantasy novels. On the face of it, Black Mirror: Bandersnatch tells the story of young game designer Stefan who's developing an interactive adventure based on his favorite fantasy book. Except he's not in control himself – the viewer is. As Stefan works on the game, viewers make all his key decisions, and he begins to suspect something is wrong.
