Been watching Diamond & Pearl. As I said before, the plan is to watch all 191 episodes plus the four movies. I don't know if it will stop there. Currently up to episode 35, so it will be a while before I get to the end. The bare minimum has been two episodes a week, with more happening when I feel up to it, but I definitely try not to make it less.
I know Diamond & Pearl is notorious for its filler. But I am not accepting skip lists. I find I tend to disagree with the Pokemon fandom at large when allowed to form my own opinions. I am watching 191 episodes to decide for myself what's important.
What most of the fandom declares filler may end up having a moment that means the world to me that I personally want to keep in future watches. Or maybe I will agree with the fandom at large. But either way, I want to come to that conclusion independently.
After that? I was thinking of watching Dawn's return in BW: Rival Destinies, Master Journeys, Ultimate Journeys and Arceus Chronicles, just to complete her story. People tell me with Ash's story done, Dawn is probably unlikely to return, and I think I agree...but I will say this; she's come back when I least expected her to before. It's improbable, unlikely, but never impossible.
