Did you watch it? What did it lack?
To be candid, I don’t remember it. It was narrated by Jack Webb. I saw it at the same time as another movie that had a nuke bomb go off in Los Angeles, followed a family heading for the hills, and I can’t remember THAT movie either. Both had clueless teenagers. The anti-commie message was clear.
People who weren’t raised in the cold war consider these kinds of movies to be comedies like watching “Reefer Madness”.
