I love Eternal Zero. I watched it twice, and I still think this movie is great.
As I'm watching it, I thought about what really makes this movie interesting for me. Is it the wonderful drama, the exciting dogfights, or the personal point of view from those war pilots? The answer: all of it. I respect war veterans, because having gone into war at a fairly young age was one of the hardest duty, not to mention how risky and full of torture it was. A kind of duty no one should undertake, because ego and greed will only lead to human destruction.
Eternal Zero gives a different perspective of war. How the main character is in all conscience not willing to die for his country. An unexpected confession, seeing how common it was for survivors to have their brain washed, so they can be patriotic in all sense, fight until the very last breath to conquer the enemy, not to holding on for dear life so they can reunite with their beloved family at home. It was pretty touching to see.
I highly recommend it, because truthfully, Eternal Zero is about human, and a view about the importance of life.
