They only did a 1 off special episode on BRT and EoT/EoD and then Sky. GTI had a 2 commercial trailer animations not episode. PSMD didn't have any at all.

I did try Generations, but it didn't hit me very well in the long run. Trust me, if they can pull if doing what they have I the main series right now, they can make a good PMD series. Same with how Generations and Origins were. It doesn't have to be canon. It could be it's own story or side story never heard of before.

When it comes to filler it's unavoidable. That's not really an issue. One issue to me as I mentioned was repetitiveness. So like, starting a new regions fresh, like he's never even started before, struggles yet improves until then end. When he just ends up choking. Then starts over as if it ever happened and he never grew and learned from those mistakes in the first place. Like Neo said, it's as if he's gotten younger in Sun and Moon's anime. I haven't seen any of the Sun and Moon anime yet, but I might check it out for curiosity sake. Maybe that Pikachu and Alolan Raichu episode. Give it the chance it deserves. .
