I think you're beginning to realize a bigger picture. There's an unrealistic image of what is acceptable in love and hollywood seems to be place that sells it. I mean it doesn't address all the problems, but it could explain why we expect what we see on tv. I didn't know I was even capable of loving someone who didn't fit the mold until it happened. I can't say it was intentional, but I feel completely different, I'm not saying we have to look for an unattractive partner in life either, I'm just pointing out that we have a preconcieved notion of what attractivness is and when we set our sights on that hollywood starlet, we're wanting what most people find acceptable, not what we really find attractive.
I personally have a hard time finding many models attractive, in the past I would point out what I liked and people would ask "why her? why not someone better looking?"
Don't get me wrong, I use looks when I decide who I like, but I can't just fall in love with a statue. That's my take on the problem. The solution is a better perception and everyone is on their own for that one.
