Query: Sophisticated Look at Why We Fight

The best of the modern epic martial arts films based on legend, "Hero" is an intriguingly structured film that explores themes of nationalism, revenge, love, and the brotherhood of man. It unfolds like a mystery--which of the several versions is the true one? Along the way, it depicts elements of the warrior ethic, letting the audience decide what constitutes honor, bravery and the greater good. And it gives us an ending to ponder at length through the questions it raises: When is war justified? What makes a hero? What sacrifices are necessary? Is it possible to achieve peace?It's also very beautiful--beautifully filmed, acted and choreographed. Whether you watch for the fight scenes or the war and peace themes, "Hero" is a rewarding experience.
