I think the writing is top notch. Building a story around a relatively simple idea is tough to do well, and they definitely, in my opinion, do it well. I didn't care for the episode with the female architect, but I'm opposed to - what seems to be - the latest trend of using children as bait in order to create tension. But overall I would give Black Mirror 15 stars out of 10.
Very interesting comment about the trend of using children as bait to create tension. I didn't realize that was a thing. It is not a good thing. I do find that binge watching Black Mirror can create a lot of anxiety as it is too close to home. I have an easier time with Twilight Zone Marathons.
I've seen the children thing a few times, so maybe it's not an actual 'thing' (there goes my exaggeration) but it's definitely appearing more. Way too tense for me.
I see you were at BEA. I had a booth in 2015. Big fun.
Were you there as an author or publisher? I like Book Con.
