Ok, fisrt of all I know there are lots of anime haters, I was one of them and still I'm with those childshit series like Naruto etc that they show on TV, but that serie has nothing to do with those crappy ones.
Samurai Champloo is a anime serie directed by Shinichiro Watanabe who has done masterpieces like Cowboy Bebop (my favourite one) and 2 chapters of Animatrix. Samurai Champloo is another of his masterpieces, it's just awesome. His series use to have around 26 chapters, there aren't heavy series like DBZ (it's shit too), or One Piece with more then 300 chapters (lol what a waste of time).
Samurai Champloo start with a fight between a ronin (samurai with no lord) called Jin, and a criminal/expirate called Mugen. Then they get arrested for killing some people and destroying a bar, so they got condemned to death, but a girl saves them in exchange of they have to go and help her to find a mysterious samurai "that smells like sunflowers".
All serie is about the travel and the shocking ending of the travel, while you watch the chapters you see how characters are and things about them past all mixed with intense action, awesome fights, and 10/10 visuals and plot.
The original soundtrack is hip-hop, non gangsta american rap, I mean sweet hip hop with some electronic songs that fits perfectly with the anime.
If you want to see it you can download it from internet or emule subed and dubed in lots of languages. I can say spanish and japanese (original) are very well dubed because you feel (dont know how to tell it) adult appearance (I mean not child voices). I don't know how the other dubs are.
Sorry for my english, I've done my best.
Here are some youtube fan music videos of the serie, and the Intro.
