How wonderful to record a "nostalgic" hour long TV show from the sixties and be completely blown away by how good it is!! OF COURSE the concept of time travel is going to involve some contrivance and exaggeration, but that goes with the genre. That said, this is a clever, engaging, and, yes, moving episode. The ending where James Darren confronts his dying father is really, really good. Excellent television all around, and well worth watching!
