I always thought it was unfair how people called her "Barbi Borg." Yeah, the actress is smoking, smoking hot. But, she played completely against that. Seven doesn't realize or care that she is hot, and she is so offputting and cold (and superhumanly strong) that she finds herself alone because every man on board is intimidated or even outright scared of her. Her quest for her humanity was a welcome element for the remainder of the show, since the doctor pretty much had already gained his by then. It seems to be a favorite Trek theme. Data, Odo, the Doctor, Seven. Even Spock.
