This is the best singular season of any "sports" anime I have ever watched, and the reason it's in captions is because this was more than a story about boxing. It was a beautiful depiction of a broken man, a man that was so successful but so shattered into pieces, it's a story of that man reinventing and reinserting himself into his past life with the help of amazingly written characters along the way. From his old companions from season 1 to newer characters that were introduced here. All of them played a huge significant part in Joe's story, and how he looks at the world, which is all that you can ask for. This was more than a sports anime, this was a masterpiece that I would recommend for anyone to watch.
To me I would give this 10 right hooks out of 10.
