I loved the "get off my lawn" line with the gun. I thought that was a twist from the usual just shouting it like Grandpa Simpson.
As for the ending, it was a bit over the top with the pose, but honestly I liked the contrast to early Clint works where he would have blasted his way out of the situation. It is as much a statement on the futility of violence as a solution as anything, which is a departure from the whole Clint genre.
Anyone ever see Omega Man with Charlton Heston? Also dies in a crucifixion pose.
