Watched all episodes a while ago, and I was greatly impressed by this series. It's definitely full of mystery and suspense, but I also like that it feels a bit different depending on which character it focuses on. And for the record, I think all actors do a phenomenal job, and especially the child actors must be noted.
Loved the 80's aesthetic and how they managed to fill it with nostalgic references to movies like The Goonies and E.T, to name just a few, without entirely banking on the nostalgia.
Definitely a great show if you ask me, and it's definitely worth a watch if you haven't checked it out yet.
