I honestly don't see anything wrong with them, sure they added more, and branched off more Pokemon((Pre)Evolutions and what not), but for me, hell, I find it all the more fun with that.
Still waiting for a baby Kangaskhan though, babies do no make babies in eggs. Well, they might be able to, but the imagery for it is just horrifying.
As for Black and White, I was a bit disappointed when I learned that I couldn't use any of the Pokemon from Generations past until I made my way through the story and got the National Dex, meaning, no A(mb)ipoms, Victreebel's, Lapras, Crobat, and the like that I always stuck to D;
But honestly, trying out a whole new generation doesn't seem so bad, even if there are Pokemon like Gear, it just gives the same feelings as your first Pokemon game; Provided you aren't a negative Nancy and/or spoil the whole list of Pokemon before you even get the damn game.
