I always felt like this game was a response to the lackluster feedback for Final Fantasy 8. "Oh, you don't want it to be too realistic or gritty or whatever?! Time for wacky fantasy everything!"
I know my circle of friends was disappointed in 8, but 9 didn't even ping their radars.
I never finished 8 or 9, but it wasn't the setting or character design, I just didn't care about the characters the same way I used to. Cloud, Tifa and Aeris were instantly my posse. Locke and Terra were a wonderful mix of sorrow and compassion set against the backdrop of a ruthless and intriguing empire.
The later games never connected with my emotions in the same way and, eventually, I just stopped caring.
