Black Mirror is my favourite TV show so I'm over the moon that this is the 2020 addition, it makes me much happier than some RMC and seeing everyone moan about it not being an RMC has made me laugh.
Black Mirror as a show is an anthology series so Thorpe Park/Merlin Magic Making should have quite a bit of creative control over the project as their isn't one set story line and more of a general theme of "the future consequences of technology". So I expect the attraction to have a somewhat original story but with loads of Easter eggs (There's definitely going to be that White Bear/Bandersnatch logo scattered across the attraction). I really hope this gets pulled off well, this could have the feel that DBGT was trying to go for with the ending.
If anyone hasn't watched the show, you can watch it in any order and I highly recommend the episodes: "Shut up and Dance", "The National Anthem", "San Junipero", "The Waldo Moment", "Bandersnatch", "White Christmas", "Smithereens" and "USS Callister". They're all on Netflix and Season 1 - 4 can be brought as DVDs (Season 1 and 2 also originally aired on Channel 4).
