As long as Misty isn't shoved back in the gym and actually is allowed to pursue her Water Pokémon Master goal, I could care less if it's a temporary reappearance or a permanent one (although I personally prefer a permanent reappearance). For the record, though, technically, bringing back Misty and Brock wouldn't appeal to just Genwunners since the Original Series also encompassed parts of Generation II, specifically Johto. It's not just limited to the RGBY crowd, and Genwunners, last I checked, consider Generation 1 to be the absolute best and everything else to be trash.
Okay, yes. I will admit I was mistaken there. Fair point.
