Just have to say, season 1 is some of the best television I've ever seen. Lots of people love the 80s, but sadly most things are caricatures.. like The Wedding Singer or The Goldbergs, where the 80s are played-up in an almost cartoonish way. This takes the 80s seriously, takes the source inspiration seriously (Spielberg, King, Carpenter and many others) and then, with a perfect 80s backdrop started telling a wildly well-written, well-directed, well-acted, and all-around well-executed mysterious story. While it relies on, or finds inspiration in existing 80s visuals, it cobbles together a uniquely original story full of surprises and suspense, all while never descending into low-brow gimmicks.
I think what really separates this from other entertainment which tries to mine my generation's nostalgia is that while the backdrop and inspiration is the 80s, it treats them with respect rather than a joke, and then layers in just damn good story-telling and phenomenal casting/acting. And that is something that really deserves notice/credit. They cast people for the roles that were actually that age, and they cast great actors to fulfill it.
Hopefully Season 2 can maintain this level of quality and discipline.
Quick Edit: however, I will say that one downside of being so good with their 80s, is when they get it wrong, it really bothers me:
