It's a brilliant story of guilt and buried secrets coming to the fore. Using the aesthetics of a western with direct borrowing from High Noon and from Sergio Leone, especially the waiting for the train scene in Once Upon a Time in the West. But in this case its used to point the complete absence of any real hero from the story. The most heroic act performed by any character in this movie is going away.

This story is a story about all consuming guilt, about petty jealousies and how sin is its own punishment. But above all it's a story of how the war doesn't end when it ends. And it's done with a very competent hand and deep understanding of cinematic media. A very good ensemble of actors, amazing cinematography, great story and superlative directing.
