I've seen the first 4 episodes of it. Not much else to say. Science fiction anthology series.
What sort of complaints? I had a quick look and saw a few SJW/feminism type complaints but I can look past those as long as it isn't blatant, insulting propaganda like Star Wars.
Those were the minor complaints I was referring to. Most of the ones I saw came from the chans and voat, and we know the average user there is going to bitch about something or other with mainstream media. I totally felt the backlash against the new star wars films as legitimate, it is just bullshit shoved down the audience's throat, but Black Mirror still has a great premise to it.
Black mirror really has a wonderful social commentary on today's usage, and future usage, of technology.
I've heard a lot of complaints about the show, but you know what? I enjoyed it. It was dark. It was really dark, and has an over-the-top approach to 1984 and there are several episodes where I sat back and was like "wow, that's how it is now".
