Mick,
I think you would find that older people may look at this film a bit different then some younger viewers. They have lived life longer and are more likely to look at their life with questions, much like George did and wonder what kind of life THEY have led.
The older person may look back and wonder after seeing this film, did their life effect others like George's did and they just didn't realize it.
This film does just that. It makes us older people think about what we have done so far and just who we may have changed during that life.

We can only hope that someday they/we all can look back and be able to say. What a wonderful life it really was!
