If you thoroughly enjoyed the show, you will be tickled by The Good Place: The Podcast. Mark Evan Jackson (Shawn) hosts it, and it's truly excellent. Lots of behind-the-scenes info from people who are truly dedicated to their craft. If you thought the characters were great, the people and writers behind them are even cooler, and you get to hear so much neat stuff about the show from them.
Michael Schur also wrote (an often hilarious) book called How to Be Perfect, about what he learned about philosophy from the research he did in order to write the show. If you get the audiobook version, parts are narrated by some of the actors from the show, and it's just a delight as a fan. I don't think anyone would become a philosophy expert from the book, but it's an introduction to it, and amusing to boot. A good book IMO.
This is going to be a super weird request for a handful of reasons, the first being that you already abandoned watching it, but for some reason I am just super curious what your review in particular would be if you watched the whole thing, just for the sake of it now that you've said that, and came back to tell us. Other reviews be damned, something about your reaction to it is interesting for some reason, which makes your opinion of it in full compelling, if you'd consider humoring us. I'm serious.
