I'm not suggesting that someone who is beautiful, sexy, intelligent and powerful has no flaws. I'm not suggesting that these women are perfect, just that these traditional signifiers of Sue-ism seem to be these things. Many such women are competitive, obsessive, bitchy, power-hungry, self-obsessed. When a character liek this is depicted in a story and everyone loves her, I find it hard to believe, yes. Women like this are often hated/picked on by the media and other women (as your statement about J-Lo illustrates).

Some OFCs can be unrealistic, but I dislike the dissmissal of strong, beautiful women as Mary-Sues.
