I grew up on the Saturday morning western serials like Hopalong Cassidy, Cisco Kid, Roy Roger, Gene Autry, and Sky King. Television series such as 'Have Gun, Will Travel', Gunsmoke, Lone Ranger, Big Valley, Bonanza, and Cimmarron, set the stage for future attempts at Western movies. Unfortunately, Hollywood has been unable to come up with a really good Western in recent years (the last being 'Unforgiven').
The John Wayne Westerns remain the standard that everyone holds all other western movies too. Few actors have been able to pull off successfully making westerns. Clint Eastwood's films (esp. Pale Rider), Lee Marvin had a couple of really good ones, Henry Fonda, Kirk Douglas, and James Stewart's roles were probably some of the best non-John Wayne westerns that came out of Hollywood in the 50's, 60's and 70's.
