Hm, the Incineroar bit seemed like they were just adapting its Blaze ability. I actually loved the ending of the movie quite a lot. If nothing else, we're always asking for the franchise to not always give us the same stuff. I thought it was novel that they broke the rules that the anime has held true to this day and did a taboo. I felt the series has earned that much in a non-canon alternate universe movie after all of these years.
