I'm old - not dead. And no not perverted either.
I'm amazed at how many people are saying Martin's character is perverted. Beauty is something that can be appreciated at any age, whether you're 5 or 50. I had my first crush when I was still in first grade, continued being attracted to women all through my young adult years, and I still find women spectacularly beautiful even if I'm twice their age.
Claire Danes is gorgeous. Attraction to beauty is not a perversion. The body might age, but the feelings are still the same.
As for her attraction for the older man - that's something I don't get. I don't understand it when college-aged women are attracted to me either, since I'm almost the same age as their fathers. I expect them to be dating men their own age, who still have young vibrant bodies, not some old fossil. But that doesn't seem to be how life works, and this movie reflects that reality.
