You should read the book. Gaiman might be my favorite writer. Pratchett is good shit too, and I usually find these collaborative books to be kind of shitty, but this one worked out quite well.Just binged this. Thought it was great. I have never read the source material so no comparison to draw there but the story was good, pacing was good and acting was good.
I liked it when the angel is defending God's plan to flood the world and kill every man, woman and child except for Noah's family, and it is the demon who is trying to stop God from killing everybody. Good stuff.
This felt like a book by Douglas Adams brought to life. The team that did this should do a season of THGTTG next.
