Deny. While It cannot be argued that BW did disappoint in some aspects, the most disappointing of those, that is, the lack of any truly significant shake ups to the metagame, could not be addressed by BW2, and I enjoyed both, and even though I feel BW2 is better gameplay wise, I certainly wouldn't say BW was a disappointment until these games came along.
Confirm The only thing huge Black and White have going for them over the prequel is story (aside from little things like powerful Pokemon early on and Day Care/Eeveelution places being available before post game).
Of course, one thing that bugs me is that you pretty much have to play the prequels inside out before you can truly understand the story of the sequels (mainly due to Memory Link). While some of the things made sense (obtaining the special Prop Case, for example), others didn't (Skyla and Elesa joking around in Mistraton). I mean, it was a cool addition, but I felt that some of it could've just been put in as regular flashbacks.
You know you read too much when you dream about flying books.
