Hm, yeah, some spoilers may be ahead! I liked the theme of game design, of a conscious pieces of code, of a dark perverse secret, of a strong female and also I appreciate all the playful references to the genre of those old tv shows. I find Black Mirror in general quite refreshing and thought-provoking. But I feel strangely unprepared to answer your question. I think I'd want to write you a little essay on the topic with some profound insight and catchy phrases hah :) What did you like about it? Do you have any favourite episodes of Black Mirror?
