From Spotlight on Science Fiction, published 2022

Without the title card, the beginning of Panic in Year Zero! could be mistaken for a family road trip comedy. It has a hip jazz score by Les Baxter and features a long-married couple who tease and flirt with each other while their teenage kids complain about being stuck in the car all day.

But as they leave Los Angeles and head to their mountain camping spot, they see a blinding flash of light. Then another. Then a mushroom cloud over the city.

The groovy music sticks around. The happy family doesn’t.
