You'll probably have to look in a rare video store, but it's definitely worth the look. Way ahead of it's time.
For WORST western, I'd recommend the wonderful William Shatner saga White Comanche. OH what a bomb....
Oh that WAS a stinker!
Also, Ron Howard's "The Missing" was a nasty piece of trash,
I kept thinking "just get it over with and put us all out of our misery!"
