On the surface, this looks like a remake of the 1983 TV Movie, "The Day After", but it isn't. The Day After was a graphic depiction of a nuclear war and nothing was left to the imagination. (Please note that nearly 100 million Americans watched The Day After on its first broadcast, a record audience for a made-for-TV movie.)
Jericho isn't your usual disaster story. A bomb goes off from a distance in Denver, but you don't see any destruction. Even what lead up to the nuclear attack isn't made clear.
All communications are cut off from the world to Jericho except one solitary morse code radio signal.
This apocalytic vision has apocalytic mysteries that keep the audience dangling. How wide spread is the attack? Why are most communications down when there's satellites in orbit?
The story, so far, concentrates on a few heroic persons who are busy saving lives and finding shelter for Jericho's citizens from radioactive rainfall.
Only the radio operator knows what the morse code message is and he lets the audience in on part of it.
Personally, I feel Jericho is a twilight zone type of story with multiple layers of mysteries. It looks and feels like the TV series, "Lost". It's a winner. Three stars.
