I understand your list. But the Eastwood ones are pretty bad when it comes to just violence for violence sake. I do enjoy the Lonesome Dove series though.
I thought Lonesome Dove was awesome too. I’d like to add Tombstone with Kurt Russell, Silverado and Unforgiven.
Josey Wells is violent - but justifiable because of the gruesome way his family died.
The movie tells a good story of what was happening to the north and south (and thise caught between the two).
It was not, IMO, violence for violence sakes - no more than The Patriot, Saving Pvt. Ryan, We were Soliders or Braveheart (to name a few) were.
