Marketing talk? Are you kidding. Look, if you don't like it whatever, but everyone that studies sakuga, animation, etc are saying that Sun and Moon is better visually than X and Y. If you watch the first two episodes I seriously doubt you'd say otherwise. It's visually fantastic right now, not sure if it'll keep up but the premiere was great. Not going to comment on that foodfight mention.
Edit: if you don't like the artstyle there's nothing that can be done about that but the animation is objectively better.
