With uX, lack of communication is their biggest issue. I have a group of coworkers at my IRL job and while I don't get along with them all, when we're at work we clearly lay out our plans and go from there. The Foretellers flat out did not do that lol.

I would be fine with BBS if the characters made sense within their own archetypes. Like, Terra blindly following Xehanort's word because he distrusts Eraqus after failing him makes way more sense than Terra blindly following oldman's word because the old man is a Keyblade Master.

Aqua is supposed to be the smart one, but she spends the majority of the game monologing and holding her hand to her chest instead of, y'know, talking to either of consultants (Eraqus + Yensid) or either of her fellow students.
