Eventually Sheriff Andy got a women’s libber girlfriend and the show kind of went downhill after that. I always liked his original girlfriend better.
Andy Griffith show jumped the shark the moment it went from B&W to color.
Was that the school teacher? I think he married her in the finale. (The first girlfriend was the same actress as the oldest daughter on Father Knows Best)
Actually he had several Ellie, Peggy, Mary , of which one are you referring?
Andy Griggith also had a fairly consistent theme that law enforcement could handle its problems with talk therapy rather than violence [and certainly, no guns.]
