Are the latest Naruto movies separated from the storyline?
Interestingly, even though almost all the Naruto movies are fillers, they are part of the storyline. Check this post.

The exceptions are the latest two movies. "The Last: Naruto Movie" is officially classified as chapter 699.5 in the Naruto manga, while "Boruto: Naruto the Movie" is in the beginning chapters of Boruto manga.
