A funny/sad commentary on the plight of senior citizens...
At the end of the movie Georges character states he likes prison.
He gets three squares a day and other privaleges.
He's getting it better than when he lived on the outside.
And the money is going to his younger relatives so they can make a fresh start.
He and his buddies wouldn't have pulled the heist in the first place if society hadn't of been so unfeeling in the first place.
So you're left to wonder whose more at fault; the bankrobbers or a cold-hearted system that provoked such behaviour?
Consequently its all-in-all a funny/sad movie.
