One of the best.
One slepless night i turned on cartoon network and came across an Anime Called samurai champloo, the only mature anime i had seen and loved was Neon Genesis Evangelion, apart from that and some episodes of dragon ball z i couldn't stand japanese animation, so Samurai Champloo made me get a little into it.
I saw all of samurai Champloo, and became addicted, so i searched for other animes with this quality, i found three which were the ones i was recomended the most, Trigun, which has one of the saddest characters ever (Vash), Cowboy Bebop, which i liked, and Gungrave.
Of all the above, Gungrave has to have the most human and rounded characters ever, NGE are twisted, perverted and screwed, Samurai Champloo, doesn't have the characters change that much and there presonality is not really complex, and as for Cowboy Bebop, Spike is just...well weird.This series has a great mixture of action and character development, i mean they actually change phiscally and mentally trouhout time, Harry is not the same in chapter 2 than around chapter 14 or 20, my only complain wold be the over the top mutations near chapter 20, also couldn't understand why maria made that last unecesary stand.
So after seeing all these masterpieces im looking for another series this good, and not crap like Naruto or yu-gi-oh, so what would you recommend me?
