I think a lot of the hate came from Tidus, which someone said was likely because he reminded people of themselves.
in fairness, I would also be pretty angry if tidus reminded me of myself. not sure that directing it at the game is the right outlet for that anger, but I'd be angry
yuna's voice acting is worse than tidus' though, she's the female version of william shatner. star trek shatner, not boston legal shatner. denny crane is the man.
