They've been my salvation during this stay home time. I am still puzzled over that weird program where everyone was invaded by insect looking creatures. Was that the end of the series? Does that ever get explained? Was it a Halloween episode? It was dreadful . I especially like when historical figures and inventions are part of the plot . I really like the way the regulars play off of each other. I will mourn when any leave. Sorry for the name change. As the saying goes, "Why change when it ain't broke."
