It's not that I don't enjoy it.. it's just that the whole, "friendship is forever," shtick got pretty old for me. However, I would like to say, I do think the storyline of B/W had much more depth than the previous games.
I mean.. with Red/Blue it's nostalgic and almost a novelty. But as for the later games, I just always feel like I'm grasping for more, you know? With each game I can't help but to want something that's directed at a more mature audience. When it comes down to it, I suppose I always like the battling more than the story. But that's not to say that one is more important or better than the other.
