So it finally happened - we have an interactive Black Mirror! This is quite something - the episode is Bandersnatch (named after that failed Imagine ZX Spectrum game) set in the 80s where you affect the decisions of a troubled programmer who is creating software based on a book called Bandersnatch - a choose your own adventure novel. You make decisions for the poor programmer chap through your remote/controller and seems like there's a lot of content based on those decisions - five endings and over 5 hours of recorded footage.
Charlie Brooker is perfectly set for this based on his experience with 8 bit computers and the like - a lot of the fun is spotting easter eggs from the past as well as other Black Mirror episodes. Won't spoil too much more - you definitely owe it to yourself to check this out as I'd love to see more interactive stuff like this on Netflix. It might be a one off - who knows? It is something you currently can't do with cable TV, so already there's a USP right there.
Think I got the good ending?
