I just greatly prefer dark hair (brown, actually) or red hair.
Blondes I can "do" but stark blondes like SJ? Eh. Doesn't excite me.
She just looks... average. The kind of woman/hottie you see on countless magazine covers and painted on the noses of WWII fighter planes.
She's hot, don't get me wrong. I mean she has FANTASTIC curves on her, but in the end to me she's just another hot blonde and nothing special.
Net result: Sideways. A wavering, grudging, sideways but sideways NTL.
