I think Serah's absolutely impossibly styled hair is what gets me the most. The mullet out back, curls on the side, and the most bizarre blend of real-life-anime bangs in front. o_<
But, I've said it before, and I'll say it again, at least JRPGs like giving long hair to their characters... Mass Effect gave you a choice of buzzcut, man-do, or short bob.
That reminded me how much I still like the hairstyle of Ashley Riot. :p
