I think that what's hurting BoBF is (I'm guessing) Disney's mandate(s) on episode and season length. It seems Favreau and Filoni crafted a show that's really meant for ~40 minute long episodes and a 10 - 13 episode season. Instead, Disney (presumably) is forcing them to cram things into a ~30 minute episode, 7 episode season format. This, to me at least, is what's hurting the show and I could see everything being planned for the longer format but Disney refusing to let them have more run time. It's probably what's (partially) hurting RR as well, he's probably not used to directing TV, esp. a show with roughly 30 minute long episodes.
