Do nice girls finish last? And do men really like b*tches?

I do not like b*tches. If someone cannot be nice, I would rather not be around that person. Sometimes women will be physically attractive, but also give off a vibe of b*tchiness that makes them unappealing to me. I do not know if it is their expressions, or their attitude, or what. Two examples are Angelina Jolie and Megan Fox. I do not know them personally, but they both give off that b-vibe that makes me feel uneasy.
