Ashita no Joe anime is an incredibly old work, and at first I was quite skeptical about it. But after watching it the whole way through, I can only say that I am amazed. This is without any doubt one of the greatest anime in history, which influenced an entire generation of Japanese and confidently passed the test of time, because its main drawback is the art, but most people get used to it quite fast.
Ashita no Joe set the highest bar for anime storytelling quality. Such cast of characters, their in-depth exploration, development is almost impossible to find. All the characters, even the ordinary drunks, are memorable here. The main character has one of the best character developments that I've ever seen across all serialized stories.
The fact is that the vast majority of sports works are built according to one hackneyed scheme. The main character is a genius with a hidden talent in his sport. He meets a stern trainer who helps and trains the hero. Then there is a meeting with the main enemy in which the hero loses. After this, through overcoming, quarrels with the coach, loss of motivation (optional), overcoming some kind of physical injury (if any), they come to the final rival, at first loses in the fight, but miraculously turns the situation around and wins. In this regard, Joe is capable of surprising (watch the first season and you'll understand what I'm talking about). It is the plot that is the strongest side of "Ashita no Joe", and also the excellent musical accompaniment (the second theme by Rikiishi Toru and undoubtedly Midnight blues will forever be in my heart). But also the background music, music for combat and in tense moments is of the highest level (especially in the second season, the music of the first will appeal to those who love the classics of the seventies). Also excellent openings (my personal favorites are the first and fourth).
I highly recommend this anime to everyone who enjoy following well-written stories and are not prejudiced against old artstyle.
