I have no problem with Michael being the focus of Disco, but yeah, there wasn't any cohesion in much of the overall storyline. (With all of its problems, I still enjoyed Disco until just after they returned from the "other place". [Trying not to spoil])

For the life of me, I still don't know what they were trying to prove with massive pivot on the Klingons. They should have made those characters a separate race and used them as a first step in positive Klingon/Human unification, in stereotypical Start Trek fashion. (I mean, the timelines and lore was so broken by Disco, anything goes at that point.)
