I think the Daldry hiring pointed pretty clearly towards making it more of a low-key drama than anything else Star Wars has been. The Mos Eisley elements don’t need to be action packed or blockbustery if they do get introduced, either.
I don’t think it should be deathly serious, because Ben Kenobi is a wry sort of guy, and the show should have a sense of humor that matches. Basically, a Star Wars show that feels a little like Justified would be pitch perfect, to me.
