Black Mirror was just put on American Netflix within the last few weeks, and after hearing nothing but the highest praise for it, I dove in yesterday.
Woah. WOAH. Two episodes in (there are three per season, as many British shows seem to be), and this is already climbing to the top of my list. This show is hardcore, harrowing social criticism centered around the effects of social media and technology on the masses. I can't wait to see where it goes in the last episode of the season, as well as Season 2.
