It's a good story, but to be entirely honest I liked the show more than the book.

There were some little parts in the book that were probably meant to be funny but were actually quite inappropriate and not funny at all.

And another quarter point removed because it's written by Neil Gaiman and I have PROBLEMS with that man, starting with how he writes women. 

Crowley and Aziraphale though??? ❤️❤️❤️❤️❤️❤️❤️ Fantastic. Amazing. Terrific. I want to see more of them.
