If you crave for more Black Mirror episodes while they are in hiatus between seasons you are in luck.
I recently discovered the series Philip K. Dick’s Electric Dreams developed by Ronald D. Moore, who already wrote a lot of Star Trek episodes across all recent franchises, and Michael Dinner. It initially aied on Amazon Video. First I almost missed it. Watching only the first episode and not reading up on Wikipedia I expected that all episodes will be like this first episode which I hated, so gave up. It wasn't until a pal asked "Hey did you watch the episode XYZ of Electric Dreams?" that I read more about the series and figured out that no episode has any relation to any other episode. Just like with Black Mirror.
It's another anthology dystopian show, although not as dark as Black Mirror. Some episodes play in an alternate universe, or just create this because of a character making a mistake. Some play in space, others much closer home. For me, like for Black Mirror already, there is always a scene or two making me think "Wait, what?!".
In my opinion, although quite similar to Black Mirror, Electric Dreams doesn't want to be a clone. It's just the story telling of Philip K. Dick which might people think otherwise.
