Not to be too critical here but the explanation is quite simple really. It's human nature to look for the "perfect" mate. It's what being a human being is about. I don't care if we live in the cave man age or 16th century or 1990s, human beings had always been and continues to put "beauty" on a higher pedestol than most everything else. By "beauty" I don't just mean physical looks, but including wealth, power, talent etc etc.But, where do we get these beliefs? Certainly not as kids, where some of our most cherished cuddle toys: TeleTubbies, Sesame Street, etc, are grotesquely 'ugly' beasts. It's the sly and careful programing that goes into the making of each and every one of us.
So many on this site, (myself included) are sad that Hunks had to be added to the mix to make for 'better' viewing. We feel cheated, believing that maybe THIS time, the Hunchback could have gotten the girl. But as Willow Rosenberg said in Buffy the Vampire Slayer, "Oh, no, he could neverget the girl...he had to many bumps and ridges on his face!
So to suggest that somehow we are duped into this culture of worshipping the "beauty" is non-sense imo. I think we're already born with that prejudice and the media, such as TV, only reflects what/ who we are as people, not because it is creating something artificial as "hunks" or "cuties" to be our ultimate goal for perfection. We already know it.
