As a whole the World Coronation series was fairly average, my main gripes being with the great and Ultra classes.
With the former, too much skipping around and wasting the opportunity to bring back characters Ash never properly beat (Sabrina was a massive missed opportunity) The Galar gym leaders were largely ignored. I still can't for the life make sense out of having Ash fight Iris out of all people in the great class.
The Ultra Class saw massive improvements with the choreography and visuals but ran into similar problems I had with the great class. Where were the Elite Four? You aren't gonna tell out of 6 regions that had them, only 2 were in the PWC? Nonsense. It would have made Ash's growth into proper champion tier more natural and believable. Ultra Class also had the speedrunning problem that the entire PWC suffered through, but it was much more noticeable there because of the significantly less amount of people in it. It became clear from the beginning of it that it wasn't gonna be this crazy long gauntlet vs elite four tier trainers and that saddened me.
The Masters 8 though? Save for what happened to Alain no real complaints here. It gave me Ash vs Cynthia I couldn't ask for anymore than that.
Ash vs Leon was peak, nuff said.
