You know those Sam Fuller movies, like Big Red One? This is one of those.

Valiant One, not unlike its protagonist, moves briskly, but in the end, says little.

An unpretentious B-movie made with A-grade effort, Valiant One packs decent action and mostly sturdy drama into the tale of U.S. soldiers whose mission near the DMZ goes haywire and leaves them stranded in North Korea.

The action looks good, and if that’s all you want from a movie, it will probably be enough to sate your appetite. Unfortunately, beyond the most simplistic platitudes, the script is unlikely to draw in any but the most pro-military viewers.
