I really enjoyed Shadow and Bone first season on Netflix, I thought they did it really wellAlmost every TV Series adapted from a fantasy novel series has been a letdown (at some point) so far for me. Legend of the Seeker. The Dresden Files, The Shannara Chronicles, GoT (ending), Wheel of Time.
Only exceptions (so far) have been Stranger Things & The Witcher though there's still time on both of these as they're still ongoing projects and I've not read any Witcher books as yet but just picked up a boxset of 8 books recently.
