This is also confirmed to be a great movie.
The filming and editing are sublime. We could easily notice on one of the big fights, the still burning ashes floating around the scene, giving us instant flashbacks to the anime. Really nice touch.
The action is great. Himura is perfectly portrayed, with all of his goofy nuances, deep honor, shame, guilt, and killer instinct. And the same can be said of the remaining characters. Sanosuke is as lovable as ever. And Sojiro is perfectly depicted in his psychopath childish assassin persona.
We feel like we could show this movie to people that have never seen the anime, and they would still love it. Great work guys.
