Soberly shifting from war thriller to apocalyptic drama to oddly sentimental buddy film, “Onoda” bears the weight of its many filmic forefathers. But as it pulls off such moves with such quiet force, it also represents a different kind of emergence.

This is essential viewing for anyone with a modicum of interest in WWII history. For the odd individuals that don’t have any interest, this is still well worth a watch because of the powerful character study at play.

Onoda – 10,000 Nights in the Jungle, which runs two hours and 45 minutes, is an achievement: a moving and multifaceted film about one man’s quixotic attempt at leading a meaningful life.

This is an exciting, surprising treatment of a story many of us have heard only in half-understood whispers. Well worth settling in for.

Here is a really well-made, old-fashioned anti-war epic in a forthright and robustly enjoyable style from director and co-writer Arthur Harari.

The light provides wordless, and conveniently apolitical, explanation for why a person might endure nearly three decades (or in cinematic terms, nearly three hours) without action.

In the end, the movie is about a delusional guy who doesn't realize he's been indoctrinated, but it is also an emotional exploration of loyalty, camaraderie, and stubbornness.
