1. The movie feeling lost without Boseman is intentional. That was the point. They were lost without a Black Panther to lead.
2. BP does pass to Shuri in the comics so the progression to her and her dealing with her immaturity and being forced into being BP played out well in this movie.
loved it. 9/10 for me and the best project of Phase 4 and makes up for the horse abortion that was Love & Thunder
