It's good but (and I don't love being this guy) it's not as good as the book. There's so much more in the book, and you really do miss out by not having the footnotes.

A lot of the story, particularly towards the end, feels rushed and confusing. So much more is made of Strange's relationship with Flora in the book, and Lacelles becomes truly terrifying. I wish they'd shown what happens to Lacelles because it's such a beautiful punishment. Alas, you'll have to read the book.

Childermass is amazing, though. I love that character, and he's brilliant in both. Paul Kaye is genius casting as Vinculus as well. I was wondering how they'd cast him and that did not disappoint, even though he did go a bit Jack Sparrow with it at times.

To summarise, read the book because it's way better, but the TV show is still a good story if you don't want to read.
