Child actors not being cringe worthy is rare. The kids in Pan's Labyrinth were great. All the kids in this are pretty good.
I love the music of the show. The show looks expensive too, which is nice.
I only watched the first episode so far. They totally nailed the whole feeling of teenage love where that boy is doing everything he can to get alone with that girl. I was the same way as a teen was rooting for him the whole time. Only period screw up I have seen so far is that teenagers did not call each other "douchebag" in the 80s.
Wynona has apparently always been crazy. Even before she was shoplifting I read that when she was not working she'd just stay in all day, order food, and go long periods of time without showering. I guess she's crazy without alcohol or drugs because I think she's aged pretty well.
