It doesn't need to be since it's fantastic. Even the plot is stellar. Bounty hunters in the future of 2071 going through a vast and new galaxy where some places fuse old world Earthly objects with the new futuristic ideals. So damn awesome on that front alone.
I plan on re-watching "Great Teacher Onizuka" later,Great anime.
GTO is a great example of original and funny lead characters. I don't think I need to comment on Cowboy Bebop's greatness..... Ehhhhh, fuck it, I'll say about anyways. it's one of the few shows I can recommended to non anime anime fans. And Outlaw Star is a really fun show, I consider it one of g.o.a.t. and it has AISHA, DAMN IT.
