Yeah, the Twilight Zone, Playhouse 90, The Dick Van Dyck Show, were great, but for every one of those great ones, there were two or three (or more) clunkers like The Hathaways, a show about a family who owned a bunch of chimps, My Mother the Car, a show about a guy who's dead mother talked to him through a car, Mr. Ed, a talking horse, My Favorite Martian two talented leads, stuck in a badly written show, and on it went.
MFM couldn't have done that badly to spawn a sister series.
There was an animated series with the same name but not sure if it was the same characters though they did have a young woman as a core character.
