Man...just finish watching the last episode and this show is great. Love quite a few things in this show from music, to character development, pacing of the story and many more. I can now see why when the show release in North America, it was quite a hit during that time.
I am not going to write too long here of what I like but here is a very brief of what I think.
For the music, I like the mix of hip-hop, rhythm & blues while at the same time mixing it with traditional Japanese music. It sound quite right in this show and quite a few of the song playing become important during important scene which make the mood even more stunning. For animation, it look great and still age well after 11 years when it was 1st shown. For the character development, they did it well on all three main characters. You have quite a bit of feeling for all of them. The amount of info you learn during the show about them make it more emotional once it reach the climax as you don't want anyone of them to die. The pacing is great. They mix quite a bit of everything in the show while at the same time don't feel like a drag as you watch it. You might watch something very serious and sad tone like the blind lady episode and then jump into comedy when you go watching the baseball episode. This keep the show fresh and moving so you don't feel like a drag as you watch.
Lastly, the show have almost everything you need to grab almost any audience, from comedy which is clever, to sword slashing fight, to emotional movement which still stick with you after you finish watching the show. Would recommend everyone to watch this show as it's great in so many ways.
Now, I am off going to watch my next show which will be Kite and Kite Liberator. Need to get that show done.
