It was good
Clint Eastwood did well since he was directing and starring. Gene Hackman was good.
I felt Morgan Freeman was a bit of a letdown. Could've done much more with his character.

To me, Unforgiven refers to William Munny himself. He killed everyone, women and children, and I think all that took a toll on him, and even if he did turn his life around for a while, he could not forgive himself. That's my take on it anyway.
Enjoyable watch, but only a one-time watch for me.
