I finished the season. I thought it a bit hit and miss. Few episodes justify the longer running time and the themes and presentation appear increasingly derivative. I felt like the storytelling was drowning in the shows sci-fi remit at times. Also it seems a bit much to expect one person to keep churning out fresh, high quality ideas.
Hated in the nation was very good, shut up and dance and the video game episode felt entirely redundant but were still watchable. The others were faintly irritating with the exception of Nosedive which was the really standout episode for me. Bryce Dallas Howard was really great; an excrutiating, touching performance that painfully conveys the tragedy of our antisocial media subjugation. Hideously beautiful. It's right up there with Be Right Back as the best episode in my view. With this and Jurassic Park BDH has surprisingly become a real favourite actor.
Not specifically Black Mirror, but why does everything have to be so long and laborious now; all limbs and outward flourishes.
