That's the problem--Disney/Star Wars is not telling compelling stories because they--like the majority of the writers behind 30+ years of ancillary market creations (comics, novels, etc.) long before the Disney acquisition are not only incapable of doing so, but their greed prevents them from realizing that as a concept, Star Wars had a finite life / story--it was never about thousands of years' worth of characters and events. Few can say that Disney/Star Wars is telling stories that have any creatively valid reason for existing, other than focusing on things that are more fan service / nostalgia (and other motives) than substance.
McGregor is a strong actor, and deliver a fine performance as Obi-Wan in the PT (by far, the best thing about the PT which has aged well), but in what was sold as a showcase for the character has made him largely a supporting character of his own narrative, allegedly "rising" to some occasion in the 6th and final episode. So far, its not coming off as a SW story anyone was asking for.
