I just finished Horizons and really enjoyed it, and I noticed that there is no movie. They have released 155 episodes but there is not even rumors of a movie.

Ash definitely has a charm that can't be recreated with Roy and Liko, not that they should, but I wonder what a Horizons movie would even look like.

Legendaries and Mythicals are so common in Horizons that a movie about one wouldn't even make much sense. And a lot of the stories of side characters are already explored in the games.

Honestly the last Ash-type pokemon movie was probably the Volcanion one. The writing of the 3 later ones were better objectively but the it felt weird having Ash and none of his companions.
