I Think ash should've stayed as a pikachu. then he really would be a pokemon trainer BADUM TISH *crickets chirp*True, but the damage had been done by that point. If the filler from the previous two were more like the ones in Master Quest, then they wouldn't merit the dislike.
Though I can't say that the Pryce episode counts as filler since it sets up the Gym Battle. If you skipped it, you'd be missing part of the story.
anyways I agree there was 2 much filler.
