Female Klingons are not attractive as a rule.
But Worf's girlfriend and the mother of his child was.
Unlike usual klingon females she had a nice row of straight shiny white teeth, instead of gnarled, yellow fangs.
She had very little klingon features other than the hair and forehead.
I just thought it was pretty bad how they made her look half human, cynical in a way.
Why couldn't Worf's girlfriend be a typical looking klingon woman? Did they think it would make her harder to relate to or less tragic?
