I know nothing about the source material, but I absolutely adored this from start to finish. It's so Tim Burton esque in terms of the eyepopping/gothic visuals and the score and if he ever got to direct a Harry Potter film, I imagine this is pretty much what it would like, especially with the darker tone.
This is easily the most expensive looking and cinematic show Netflix has ever put out there and man what a stacked cast many of whom I had no idea where in this which was a nice surprise.
I really liked the lead guy and Boyd Holbrook who really got to chew the scenery in this, and you could tell he was having a lot of fun doing it, but I could have used more Charles Dance and David Thewlis.
I'd definitely love to see a Season 2 and see more of this amazing world.
