Tell me what was your first decent Final Fantasy? You probably don't like change. But imo X is one of the best. You can't tether yourself to a set style.
About X, you look at the glass and you say its half empty, I look at the glass and I say its half full. (SPOILER)You DON'T know that Yuna is going to die. You DON'T know that Auron is unsent. You DON'T know that most of the key charecters are unsent. You DON't know that the Al Bhed are kidnapping the summoners because they don't want them to die. You DON'T know that your dad actually likes you.
Half of the things you said were obvious (Yuna and Tidus get together, Fight sin at end, Seymour evil). Wait thats more than half. The other (Kimhari and Tidus friends) you already know that Kimhari is Yuna's guardian so obviously you are gonna be friends.

EDIT: Mark your spoilers. -Murder
