I don't want to sound like a troll, after thinking about Cowboy Bebop, it makes me a bit sad and empty.
Spike doesn't really care about anyone. He's kinda self-seeking, I think. He's cool only because he has an afro and kicks butt very well and efficiently. But as for his attitude, I find him nihilistic and that he would care less if he died. Then he dies.
Vincent (from the movie) is about the same. He actually wants the world to die, though. He kicks Spike's butt pretty well and has died before (like Spike), wondering if life is just a dream...
And both of them die. Bang.
Sad. Anyway I enjoy the show because it's very creative and musical, but I don't like Spike and his outlook on life. They feel empty...
This is how Fruits Basket became my favorite show. hehe
