It really bothers me when a woman in porn is a "star" based on nothing more than her looks.
You've got women who weren't/aren't the most beautiful or endowed, but who worked their asses off (both figuratively and literally) to put on the best performance.
In other words, I don't like lazy pornstars.
I know it's heresy, but Christy Canyon always struck me as someone who simply got by on her looks. Fantastic body, but she seemed like she'd be a lazy fuck.
