I've seen all these. My favorite is deff. Inuyasha. The characters in it r kool, and Inuyasha kicks butt. However, trigun is also cool. I havent seen as many episodes of trigun as Inuyasha. But og what I've seen, I'm happy with it. As for cowboy beebop, i have seen it a couple of times, and I feel that the show goes nowhere. It has a storyline that does not change ever. It is a constant, ongoing story, about 1 guy, with his crew. All most like a boring biography.
But james, Inuyasha is different than DBZ. The difference is that DBZ is the same thing, the Z fighters need 2 get stronger 2 defeat the monster that is destroying the earth. Inuyasha is an ongoing story, that gets pulled into substories. Much like Kenshin
