I finished reading The World of The Orville last night, and the last chunk of the book wasn't quite as good as the rest of it. It was focused on the new setting and aliens introduced in each episode, but it didn't really go into that much depth about any of, so a lot was stuff you could more or less pick up just from the episodes. There were still a few interesting bits of information, like what locations they used for some of the exteriors, but not as much as the stuff focused on The Orville, characters, and the Krill.
Still highly recommend it for an fan of the show though.
I need to get that book. Hopefully updated.
