I'm not sure how many times this theme-- person from one century suddenly and inexplicably transported into another one-- was covered on "Twilight Zone" but I'm sure it had to be at least a half dozen times. Rod Serling wrote this particular version, and it's not one of his more inspired creations. Basically, the plot boils down to (spoiler alert!) a pioneer from 1847 with a sick son and Gomez Adams (John Astin) as part of his wagon-train crossing a hill in New Mexico and finding himself suddenly in 1961. He is astounded by the trucks and power lines, has a drink of water at a local diner, and is examined by a doctor played by Ed Platt ("Get Smart") before grabbing a vial of penicillin pills and returning to 1847, saving his gravely ill son, who in turn will grow up to invent penicillin (although not in time, evidently, to save guys like Winston Churchill's Dad or Al Capone, and I think Alexander Fleming could have sued Serling, had he not died a few years previously). What saves the episode is Cliff Robertson in the starring role. He is, as always, excellent, and the episode is worth watching for his presence alone, if for nothing else.

This is one of the episodes I initially didn't care for, but I liked it much better the second time I saw it. I pretty much agree with the previous posts. This is another one of the many great time travel stories from TZ and Cliff Robertson does an amazing job. Of course, there are tons of great TZ moments, but one of my all time favorites is when Cliff Robertson's character finds out he is in 1961 and the lady at the diner drops the dishes. That scene for me, had a lot of impact.

Not meaning to sound like a broken record, but this is another example of what Twilight Zone seemed to do best - time travel. By the way, can you believe that one of the actresses in this episode was named Evans Evans? I wonder how that happened.

Very strong, particularly due to Cliff Robertson's performance in the lead role. It's story is familiar ground for the series, and its done better in other episodes, but this is still solid.

Another masterful example of Rod Serling uses Time Travel to weave a complex and thought-provoking story.
