Because you still can't know how a show will turn out when you buy it. You are often buying a show based on some scripts or based on a pilot. Pilots are, generally, not a good representation of what a show can be. Often they can be weak because the actors and writers still haven't found character voice etc. With rings of power they bought some licenses for an IP THEN made a show... at that point you have a significant sunk cost and there is pressure to get SOMETHING made. Maybe some of the actors are weak on the show, maybe the show just looks bad once you get it, maybe qualitywise it's fine but it just doesn't click with audiences.
