I played a Pokemon White ROM for 10 minutes before I turned it off. I really can't stand the newer revisions.
One of the reasons is the multitudes of Pokemon. There's just too many. Also, I hate the lack of creativity in the new Pokemon. I mean really, Garbodor is a pile of garbage... Also, the newer Pokemon just don't seem to fit in, and just seem to me like an add-on made to up the price of new Pokemon games. I haven't seen one of the generation V Pokemon that would fit in with the first generation. Lastly, it feels like the game guides you too much. I liked the idea of a puzzle; having to figure out what you need to do next on your own. Black and White just seem to direct you to the next objective without letting you plan your own game.
