What the heck is filler in this context anyway, there isn't done overarching goal to be reached, THIS is the goal, THIS is the main point of the saga. I wish people would knock it off with spamming that term incorrectly because they see an episode they don't like , it's so asinine
A filler is a meaningless and pointless episode, the quality of the episode doesn't matter, there are plenty of episode that are of good/great quality.
I guess people can find meaning in quality episodes regardless of the content, but this a subjective perspective.
But I'll say this again, and I'll have to say this again later most likely
I would rather have episodes focused on the main characters. Very rarely do I want to see random wild/other trainer's Pokemon get focus. The point should've at least been to give Go his starter (but at least that's next episode) and for Ash to get another Pokemon, and the focus should've been on that.
I'm tired of episodes where we get a Pikachu episode, that's primarily about other Pikachu than Ash's Pikachu (for example). If I want a Bulbasaur species related episode, I would rather it deal with Ash's Bulbasaur.
I don't care about meaningless/random/wild/other irrelevant trainer Pokemon, I just don't get why the series has to primarily focus on them this series. Legendaries/Mythicals are one thing.
Take the Hawlucha episode, the Shiny Hawlucha one, one could argue it was meaningless/pointless, but it was still heavy focus on Ash's Hawlucha and such I prefer those episodes (filler or not), than a hypothetical episode about a shiny Hawlucha being the primary focus and Ash's Hawlucha is nowhere to be seen or barely shows up.
