Sadly, I believe Black Mirror has been running on fumes since the end of season 3. I think I described to my friend as a Charlie Brooker keeps building the same house but giving it a different coat of paint. Ever since the show literally peaked with "White Christmas" (which is undeniably either the best episode of the show or in the top 3), they have kept repeating the "torture AI" concept. This became intolerable for me when I reached "Black Museum". I like a lot of episodes that go for something new, like "Metalhead" or "Shut up and Dance", but the amount of episodes that keep refreshing old ideas is starting to get tedious. However, the worst episode of the show was either "ArkAngel" or "Black Museum". Jodie Foster seems like a nice person, and I haven't seen many of her other directorial efforts, but I think she made one of the most boring episodes of the show, on par with the first half of "White Bear" which was intentionally bad. "Black Museum" is like a bad remaster of a game you like. There are other types of technological horror stories you can tell, "Shut Up and Dance" proved it, but they keep resorting to the same beats of eternal hell inside a computer. I think the show needs new writers and a new showrunner ASAP. The show is also limited by the gimmick, that being technological horror stories. This has really limited the writers creativity, unlike Inside No.9 which has a simple one location gimmick, which gives them more freedom. Honestly, for a show written mostly by two guys, Inside No.9 is a much more creative, shocking and impressive British anthology tv show. So just go watch that. Its less tedious and annoying.
