This isn't the only downfall of this anime. The animation quality is okay for the most part although for an anime with plenty of fighting, the quality of the fights is sub-standard. Instead of transforming the intense fights from the manga into fluid animation, all that's produced are static images of impact that just looked like a page straight out from the manga, which is definitely below the level of animation of it's time. If more effort was put into the numerous fight scenes then I would have given it a much better score.
The music ranges between really bad and sublime. There are times when the music is so great, with string instrumentals making the average fight seem more intense. Then there are moments when the music is just plain awful, like the deafening ending theme song "Ashite ne moto".
Overall this anime did a great job in adapting the superb manga story however it only told half the story, leaving major plot changes and character developments untold. The way it chose to end was poor, with an extremely stupid finale which followed a sad and exciting episode… bad idea. If only this anime does the same thing as others like Full Metal Panic, and make a sequel that looks 10x better than the original. Well at least with the story it has, it was able to portray Action, Drama and Comedy well. So if that's what you're looking for then this is the show for you.
