Not bad — I’d never read anything by Terry Pratchett before this. I like his style of writing, and the ideas brought up here and there in the book regarding religion are thought-provoking.
Sadly enough — because I really wanted to really like this book — I’ve never been a fan of the “all satire/funny” style of writing. Give me some Heinlein (with the witty banter of his characters) or something more modern like John Scalzi (who’s a LOT like Heinlein in how he writes) and I’m fine, but the type of writing in Small Gods (or something similar like the Hitchhiker’s Guide to the Galaxy) just bothers me. I’ve never liked it.
Maybe when you try for the joke-a-minute style of writing that sometimes it can’t help but seem forced, or the jokes kind of just start losing their funniness after a litle while (I had that problem with Hitchiker’s Guide — near the beginning, I’m literally laughing out loud while reading, and about 2/3 of the way in, I’m like okay, get on with the story).
