WITHOUT GOING INTO SPOILERS but I think BOOK READERS probably know why they're doing one episode a week. They don't one someone binge watching and tweeting about The Big Moments while everyone else is still on episode 3 or whatever.
Yep, which means they aren't adapting the last three books, unless they do them as a mini series or something in a few years. Cas Anvar gone too. I think they should just say Alex has gone back to Mars rather than recasting for just one season.
You can see why they did three episodes for the first week, as they'e mostly set up for the rest of the season and it's good to get all that done in one week and get to the big ending (poor Fisherman with his cool glasses!) The Amos stuff did work as a standalone story though so that was good! The moon looked cool. Drummer is the bisexual pirate of all our hearts. I enjoyed these opening episodes of the season.
