I’ll go with Lonesome Dove for my all time favorite, but I love the spaghetti westerns- with the fantastic late, great Ennio Morricone.
Will Penny with Charlton Heston and Joan Hackett is a favorite of mine. Nice characterizations.
My bizarro world persona enjoyed
The Terror of Tiny Town ( a western with midgets) and Zachariah The First Electric Western with Don Johnson
Ennio is dead?
