First things first... this film is STUNNING! ?✨

Everything about it is beautiful and really brings the manga/anime to life in this adaptation. The ACTING is impeccable, every scene flows beautifully and is so believable for me as a viewer.
Next, I love the COLOR, and lack there-of. Every color that is present in this film provides so much purpose and passion for the story, from the boxing gloves all the way to the dresses and suits. Which leads me to the costume&design, that is simply perfect for placing the audience in that time period.
Lastly, the CINEMATOGRAPHY, which again contains amazing angles, close-up shots, and rack focus throughout the entirety of the film.
It's really for these three reasons that I think this film is sports masterpiece!
