Binged the first 3 episodes last night. No spoilers.
I like it but don't love it. The production design (and production value) is incredible. The performances are uniformly excellent.
The writing and directing is shaky, I think. The games are violent, but rarely sadistic, which the show frequently is. The games are cynical about institutions but generally optimistic about human nature and individual people; the show feels cynical about humanity on every level (which is not surprising coming from the Westworld show-runners).
There are what feel to me like too many "do you get it, dumb audience?" moments, but in fairness some of those might be less grating if you're not familiar with the games - but some would be grating regardless, I think.
