I thought the Star Wars franchise had bottomed out with the Lucas prequels, then came The Last Jedi. Surely, that is the bottom of the barrel. This is hard to predict. The GOT crew specializes in subverting expectations. I expected season 8 to be good. They managed to subvert my expectations. I expect their Star Wars effort will be terrible. Maybe it has a chance of being good.
Rian Johnson specialized in subverting expectations as well. Star Warts is dead, Jim.
