This is a suggestion, of course some of the program suggestions could be replaced with other shows, but I think to stay family friendly is the key. Also not showing any program for more than 1 hour at a time would also be beneficial as it would not tire people out of one program or run you through an entire season or series in a month.
Some other shows that would be good on Hallmark would be The Honeymooners, McHales Navy, Wings, Alf, The Phil Silvers Show, Father Knows Best, The Donna Reed Show, The Patty Duke Show, Make Room For Daddy, Hogans Heroes, Andy Griffith, Amen, The Cosby Show, Bewitched, Gilligan's Island, Family Ties, The Flintstones, The Jetsons, The Bob Newhart Show, Newhart, Barney Miller, and The Waltons to name a few.
