You have to learn a word to understand the movie completely. 'Seppuku' - which means ritual suicide committed by a samurai. So that is why it's called 'Hara-kiri: death of a samurai'. You must have patience during opening sequences, without character and story development you will be in a tough position to understand about what's going on. While the story and character progress with the development you will start to get and you may fall for the emotion parts if you are a tenderhearted. And also you will be uncomfortable during 'seppuku' scene.
Takashi Miike's career best, this is what already everyone saying about it. But Its to hard to say which was his best, I like many of his works. I might be overwhelmed by the watch but will be happy to recommend it to others. I was very little unhappy for the ending scene otherwise I could have said it is the best of Takashi's work.
I am so curious about Takashi Miike's upcoming and Hollywood debutante project 'The outside' with Tom Hardy. Expecting it would be another 'The last samurai', I wish a good luck to the team.
