What "drama and edginess" did Kanto/Orange/Johto have? It's far more likely that your waxing nostalgic and putting them on a pedastal rather than actually viewing them for what they are.
You know, the exact same thing can be said about people talking about AG and DP. And anyways, I watched the Kanto saga, and I didn't even get nostalgic about it. I did feel they were legitimately the best. Of course, even IF I did feel nostalgic about it, I'd prefer that than, you know, pulling a newspaper-ignorant kid from opus and forgetting about it despite having watched it and had it been prevalent.
Trust me, I grew up with those episodes. They aren't all that great. Fandom seems to agree that Johto is full of fillers, but I'd argue that Kanto is much worse.
So, umm, question. If Kanto was worse than Johto, wouldn't that mean that the rest of the anime, you know, wouldn't go beyond Season 1, or even halfway through? I mean, Kanto was what started Pokemon in the first place. Saying it's worse than Johto is like saying the anime in itself is terrible, since Season 1 is what started the anime in the first place. Take it out, and you won't even have a show.
And don't try to accuse me of being nostalgic about Season 1. I watched Season 1 fairly recently (second time overall, first time in roughly nine years) on June, my opinion of it was close to it was back then, so I'm DEFINITELY not being nostalgic when I say it was a very good season. I think Nickstr also has this experience as well.
So, how is bringing the original characters back change anything? It would get incredibly stale seeing the same people in every episode. Not to mention, Misty and May have their own lives which doesn't include following Ash around for the rest of their lives.
Well, at least it would get less repetitive. Besides, Brock's still traveling with him, and heck, technically speaking, even JJM is traveling with him. In order for it to not get incredibly stale, there should not be running gags, AND they need to replace all the characters every single time.
And anyways, he definitely knows what he is talking about, seeing how he had looked through both the American and Japanese ratings of the original series, AG, and DP, had to analyze their overall ratings (or in the case of DP, the ratings up to that point), and determined, quite logically, what their true popularity and worthyness was. He also checked the ratings on Pokeani, as well.
