There are a lot of westerns i havent seen; however it is one of my favourites genres.

1. Rio Bravo (Howard Hawks, 1959)
2. The Wild Bunch (Sam Peckinpah, 1969)
3. The Searchers (John Ford, 1956)
4. The Tin Star (Anthony Mann, 1957)
5. My Darling Clementine (John Ford, 1946)
6. Unforgiven (Clint Eastwood, 1992)
7. "There Was a Crooked Man..." (Joseph L. Mankiewickz, 1970)
8. The Good, the Bad and the Ugly (Sergio Leone, 1966)
9. Man without a Star (King Vidor, 1955)
10. Johnny Guitar (Nicholas Ray, 1954)
=. Stagecoach (John Ford, 1939)

I think the tin star is an overlooked western
