The Waltons was plagued with a host of continuity issues. Season one was near perfect but then after that it went off. Certain thing like having Earl Hamner Jr. say that they would never see a traveler again and then a season later the traveler is back but as a different actor. Their timeline was also something of a space-time continuum mess.
And for different actors they win a prize. About 15 characters were played by different actors and I'm only on season seven.
Elizabeth is turning thirteen and gets haunted by a poltergeist. They try to explain it that when young kids go through a "change" ghosts get attached to their energy until their inner conflict is resolved.
The episode had flying furniture and everyone taking this serious. It was hard to watch especially knowing the actors were probably disgusted at the whole thing. Granted Earl Hamner J. did a few Twilight Zone episodes but if they wanted explore the supernatural they could have done it better.
The Warrior: Had an Indian burial ground under the Walton's barn. The entire episode was sketchy and the Pa Walton's reaction was uncharacteristic to say the least. Still it was nothing compared to The Changeling.
