If you count the endings, Panam has just as much content as Judy. If you disregard the endings, Panam actually has less content than Kerry, and much less content than Judy. If we only count mandatory content, Judy still has more content than her. So, there must be another reason why you hate Panam because it can't be that she has more content than everyone else, since she doesn't.
