I guess I love everything that's everyone's already said. (Battle and Sphere Grid and such) I too disliked Tidus and Yuna but I love it how we get to watch them grow up and mature in to independent people. Same with everyone really. Except Auron who pretty much already knew everything there is to know. But now for the ending. I didn't just shed a tear. Or even cry for a while. I threw myself to the floor sobbing and Screaming "WHY?! WHYYY!?!?!?" No joke I swear it. I didn't leave my room for days. I just slept, stuck in deep depression. And that's why it's so great. The effect it has on you. ^^
I cried quite a bit...it was very sad and depressing, which is what makes it great. I liked Yuna and Tidus......Tidus just isn't one of my more-liked FF characters...however, I really did like Yuna alot.

And I just kept thinking of KImarhi as Yuna's big stuffed teddy bear for some reason.
