Just watched this and was blown away. When a filmmaker thinks of a dramatic scene and builds a film around it, they feel pressured to make it as referential to film history as possible these days. This film is direct with its few chapters (its based on the story by Mishima who also directs, adapts, produces and stars). Only a few things actually 'happen', but they are filmed perfectly. The absence of dialogue is perfect; you'll forget that films normally have it. It's that engrossing. Be sure to also check out Mishima: A Life in Four Chapters.
The extras are very interesting as well. You'll want to here/see this man speak after watching this film.
