I liked the 'flavor'....
I liked the 'flavor' of the black and white shows. They did a great job with the stories in the full hour format but as the years went by the flavor went from 'gritty' to 'cosmopolitan'. Still a great show, though. Like I said, I used to love Bonanza, but they've worn thin, while Gunsmoke just goes on and on.
Also, for some reason, 'The Rifleman' never seems to get old. I think that's thanks to Chuck Connors, who seemed to have an aura around him.
I used to think 'The Rebel' was good when I was a kid, too. Until I realized that they were making a 'pretty boy' "Rebel Without A Cause" in the west. I liked Nick Adams more in the 'Outer Limits' episode "Fun and Games". One Rebel episode that sticks in my mind is where the crazy old guy started laughing like a banshee and when he moved out of the way the window was full of Indians with their weapons pointing at them.
The"Wanted-Dead or Alives' are good and McQueen was a great actor, but his choice of weaponry seemed wrong for the mission.
