Black mirror has a unique vibe in its episodes. I really, really enjoyed the first 3 seasons. Season 4 had some great episodes, also some less entertaining episodes. But season 5 doesn't feel like black mirror at all. It seems like the technological dystopia that every great episode had, was not recognized in season 5. It felt more like 3 short mainstream films to me. Season 5 just wasn't dark enough and it was too expectable. The acting is good don't get me wrong, but the stories in the fifth season aren't like they were in seasons past. Seasons 1-4 a solid 9, season five a 6, but in terms of relevance to black mirror, I wouldn't even rate it.
