I'm not familiar with Philip K Dick stories so I can't comment on that. But if I compare this series to awful dark 4th season od Black mirror I can say that I'm enjoying myself much more watching PKD Electric Dreams. It's futuristic and diverse. Maybe a bit more drama then BM. Can't complain with casting Steve Buscemi, Bryan Cranston or Anna Paquin.
