It has been about a year now since I watched this series. I was never much for the sports based anime, but I really like amrtial arts and thought that I would give this series its fair chance. To say the least, I was impressed witht eh show overall. Every episode kept me wanting to watch more. After the end of 75 episodes, I was pretty happy to find out that there is another series and movies to accompany the ending. One of the strongest points of this series was the fact that you could complete the main series and not feel that the show was left completely unfinished. It did leave the door open for continuation but not in the traditional cliffhanger fashion.
What made this show such a strong contender was the development of the main character as he begins his career in professional boxing. The way that the writers demonstrated the trials and tribulations that he faced as he was on the path to becoming a boxer felt very accurate from the stand point of someone who has gone through similar rigorous training to attain a high level of competition. What was also positive is the fact that you don't have to be into boxing or sports even to really enjoy the story here.
I would really recommend this series to anyone who enjoys stories about overcoming adversity to achieve high goals. This was definitely a series that topped my list of ones worth watching a second time.
