Don't get me wrong, I like Ash! He's my childhood. But I don't like what has become of Ash under this philosophy in the anime.
I'd be fine with them focusing on the girl player-characters. Actually they're the ONLY ones they've focused on, since Ash has been a constant. So it's been gen 1 player character (Ash/Red) and SOME of the female player characters (May, Dawn, Serena).
I'm very glad they're going back to where his character was fresh in the movie (presumably). But I think we could have accomplished everything the anime wanted to without having this massive problem of continuity issues. And think how exciting it would be to have had Ash return in future seasons as an older pokemon master to guide the newer generation. Or heck, have an older more mature Ash as the focus of a more adult themed series!
