Rousseau's first and second discourses are great readings on this. Most people wouldn't discount either though.
As for genetic counselors...it's a toss up on virtually every aspect of eugenics. The opinion in many places is that parents are to be given the choice in whether they want a child with a life-altering disease. Some people play up movies like Gattica. However, controlling most cosmetic features and athletic or intelligence abilities are beyond our control at this time. It's believed that certain human features don't have genetic links, and certain others are complex linkages (many genes regulate each other producing several phenotypes at once).
Oh and the girl (Uma Thurman?)in that movie wasn't bad herself
