Viva Villa! with Wallace Beery is a favorite.
There is nothing on the list so far that I wouldn't sit through. Open Range and Lonesome Dove get 5 Stetsons from the WD film critique institute. I need to look into "Hell or High Water." My mom used to say that. I need to know what she was talking about.
I like all the Spaghetti Westerns. I'm a cheap date.
