It's rough to judge black mirror for the first episode. I had. Ahard time getting into it as well, and even when i was fully hooked, i could only watch like an episode or two a week, because it IS pretty depressing. But it's also thought provoking and there are episodes that just live in my head, in a good way.
Oh, that one was... yeah, I would not have been hooked off that one, personally. I would definitely reconsider if you're at all willing. Maybe try Black Museum. Hmm... not sure of which you might like the most, but USS Callister is widely renowned, as far as I know.
The entire premise seems too preachy for me. They really kinda beat you over the head with it. And are usually kinda victim blamey, from the bit I've learned beyond the one episode I watched.
Rather, the overarching idea in Nosedive is that the flawed system pushes people to misbehave in terrible ways; it encourages you to step back, zoom out, and be more in horror at the whole thing from the start to end, rather than just at the protagonist's actions. Same with the episode White Bear, etc.
Dodged a bullet with the Witcher—the show went so off the rails with the source that it’s not even worth pretending it’s an adaptation. By all accounts the same is the case with the wheel of time but I have no first-hand knowledge with that ip.
