Harakiri ★★★★½

This is the best samouraï movie I've seen so far. The one who is truly about character more than it is about sword fights.

There is a quote I like from Ted Chiang, the writer behind Arrival (2016) which says "To me science fiction isn't about special effects or giant battles of good versus evil. Science fiction is using speculative scenarios as a lens to examine the human condition"
I like to believe that quote applies to all genre. At least, it perfectly applies to Harakiri within the samouraï genre. As the story of the man coming to commit seppuku unveils, it reveals a deeper story than first meets the eye.
My only nitpick was that despite the originality of its concept, it was rather predictable. Also I often find characters in these films too contained. But overall, there's little to hold against this masterpiece. Almost a 10/10
