Ok Think about this....
Clint has been known as One of the best tough guys out there..At least he has portrayed that in Most films. So, here is my thought of this film. Being The tough Guy Character he has portrayed for all of theses years here is his Toughest Tough Guy Role: How does a Real tough Guy exit this World (Character)? He found the way. I think that this movie is about Him ending a Complete chapter of his acting career from start to finish. That was the best exit Ive ever seen. He showed that he, as a person aged with wisdom, having a temper and all.. Great film probably one of the best ones he has ever done.
I will miss him as an actor on the big screen,
