Underrated agreements: FF2e/4j sucks; just admit it. Also, acknowledging that there are a lot of bad points in FF7, despite the fact that the game is still awesome.
Disagreements: FF9, which I was never attracted to at all. FFX-2, because the story was such shit that it wasn't really worth going through the decent gameplay. KH2 was still a really good game, and actually fixed some of the annoying factors in KH1. No love for Secret of Evermore, either. It's not as good as SoM, but it was still a good game in its own right.
I think most of this list is solely based on gameplay. IOW, if it has shit story and good gameplay, it's a good game, but if it has shit gameplay and good story, it's not a good game. Most people who are playing RPGs at least need to have a good story to carry along. Otherwise, it's not worth playing.
Rosalina: But you didn't.
Robert: But I DON'T.
Rosalina: You sure that's right?
Robert: I was going to HAVE told you they'd come?
Rosalina: No.
Robert: The subjunctive?
Rosalina: That's not the subjunctive.
Robert: I don't think the syntax has been invented yet.
Rosalina: It would have had to have had been.
Robert: Had to have...had...been? That can't be right.
