We're all show-only now. Only the first season was an adaptation of the book, season 3 will be an adaptation of the unwritten sequel to the first book Gaiman and Pratchett never had the chance to finish before Pratchett passed.
Season 2 was also entirely original straight from Gaiman. He said he felt there needed to be a bridge between the published book and the sequel they planned, so he wrote a story on his own to do that, and that's Season 2.
Season 2 really felt like a stopgap measure to pad out the series, didn't it? I appreciated the character bits but I'm hoping the final season brings more substantial story to the table.
Yeah, it got dropped with very little fanfare. Was freaking strange.
I only caught on to it because I saw a meme on Reddit that featured Crowley and Aziraphale and I had no clue what it was from, while I've watched the first season a dozen times already and practically know it line by line.
Kind of good news, at the same time they completely changed the premise of the show and have basically been flogging a dead horse. Radcliffe in sequin assless chaps definitely made up for it though!
You're absolutely right, Good Omens has a similar Christian premise but is going far stronger. I was thinking the other show had already milked a 3rd season!
Season one is based on the book, season two is still co-written by Neil Gaiman and is apparently based on an idea that he and Terry Pratchett talked about for a sequel, and I have no idea about season three lol.
Season one is based on the book. Season three is based on the sequel Pratchett and Gaiman had planned together, but never fully written or published. Season two is a bridge to fill some gaps written by Gaiman alone.
