Despite the fact that the story isn't happy at all. It gets REEEALLLY disjointed because of that. Take an early example. In the Enchanted Dominion Terra is tricked into thinking he stole Aurora's heart. That fits, because at the start of KH she has already had her heart taken... except they NEEDED the world to have a 'happy' ending, so Aurora's heart is freed and Maleficent is defeated. Uh... yay? All of Terra's Disney missions after Enchanted Dominion deal with him accepting, fighting or otherwise triumphing over the darkness. And we all know how that turns out. I hear people say this is an attempt at contrast or irony, but it really just makes Terra's fall come more out of nowhere. Meanwhile, all of Aqua's missions have her following after Terra, most which end with her noticing he did something good and being reassured he won't fall to the darkness... so why is she so accusatory when they meet up? All in all BBS is a sad story, but somewhere along the line half the script was switched out for a normal KH game. The end result is a ridiculously schizophrenic tone.
