It’s not a ‘one or two episodes’ kind of thing tbh. I am not one hundred percent it sticks it’s landing, and it gets a bit rushed and muddled in the end build up....but it’s definitely very very good and worth watching. It works best if you have read the original, but the film also works to some extent alongside.
No, it didn't get the ending 100%. The show could have withstood one more episode to flesh out the "villains" so they didn't feel so two-dimensional in the end. The problem is where would you stick that episode without breaking the momentum that built up during the last third of the season.
