The only thing that I didn't like about XYZ's story in comparison to the XY games is the lack of Xerneas and Yveltal. The Diancie movie did not do them justice, unlike the Creation Trio, which got a bunch of movies and appearances in the main anime.
Tbf though, it's not like the XY games even did much with their legendaries.
Yeah it's the only series to date I believe (not sure about OS) but the weird part is that they included the legendary birds in the series barring Articuno when there was no need for Kanto promotion.
Speaking of movies, I really hope they bring back to the main cast having movie roles. I enjoy the "movie art style" they use. The companions look nice in the original and I'd imagine JN movie art styles would nice.
point. Ignore the music. The only time they're really allowed to experiment in the art style is in movies like "The Power of Us"
and enough A.U, Ash movies. They can't even reference them anyway like DP movies in the series and just having Ash alone is boring,
