There’s a difference between constructive cynicism and edgelordism. It’s one thing to have and promote a cynical view in the face of utopianism; to jump onto the tail end of an existing backlash is far less useful.
Black Mirror, while well-made, tends toward repeating media criticisms that were already cliche in the early 90s. When your complaint is twenty-five years old, repeating it without adding anything is of limited utility; Black Mirror doesn’t introduce new and interesting twists to its complaints, and it doesn’t reproduce anything *but* the complaint.
(Now, I don’t hate Black Mirror. It’s like rewatching The Twilight Zone: everything is predictable, but there’s really excellent atmosphere.)
