And one of my all time favorites but not a movie per Se is the made or TV mini series Lonesome Dove with Robert Duvall and Tommy Lee Jones.
Yup. I’m a big Lonesome Dove fan. Though after Gus dies, I lose interest in watching the rest of it.
also liked the quick and the dead for its popcorn qualities, not a 'serious' genre western but still fun
