I liked it
Being a history nut, I love movies like this. PROVIDED they are accurate.
The love story didn't need to be a part of the movie, maybe just a little to explain why he spoke Japanese and liked the culture so much, but she didn't need to be in 1/3 of the scenes.
However, I wanted to learn more about why Hirohito didn't hang. I am (was) of the camp that he should have been, being overall ruler and "god" of the country.
However, I did learn something new. The Kyujo Incident was not known to me. This makes the movie overall a giant success. By the end of the movie, I would like to think I would have spared the Emperor as well. The coup proved that even the Japanese didn't really consider him a god (at least not those in power) and he had to go along or else it would be his neck. I had no sympathy for him before I saw this movie. I then researched it more to make sure it is accurate.
Is it a good movie, no. Is it worth watching, yes. This part of US history (45-50) is not mentioned much in USA history class. And this movie helped to solve some of this.
I know we will never know the whole history of what happened, but I would like to know if he really said that to MacArthur in English as it was portrayed.
