This is the first episode of season 4, when TW episodes became one hour long. It explores a frequent theme for the show: a person confused by his whereabouts and trying to figure out why things aren't as he remembers. Excellent nightmare material. It's one of the few episodes that touches on how annoying and/or scary someone who is ultra-religious can be. For regular Twilight Zone viewers, it will probably feel a bit drawn out at times, as though it was originally the usual 23 minutes but extended to fill the new longer time, but for someone not a regular viewer, it's a good, creepy story with plenty of surprises and it serves as a great introduction to the show.
