It's got a pretty good foundation to be a great show there were times that I found myself fully hooked and starving for more and times where I'd rather be scrolling through twitter. As a black mirror fan I thought I would give it a shot because its that same "future of tech theme" but it just isn't as polished. Times where they didn't take themes far or dark enough, and other themes were just way too shallow. The acting was pretty good I thought, with the exception of some of Kate's scenes I thought the actors were superb so I don't understand all of the complaints there. The biggest complaint I had is that there were some decisions some chatacters made that were extremely questionable at best. Anyone with a bit of common sense would have made better choices.
All in all if you're a fan of black mirror it's worth giving a chance. Once you're about half way through if you don't feel the urge to watch more and more then probably put it down because the 2nd half was less enjoyable than the 1st for me
