yeah, shininchiro wantanabe really has done some of the most amazing animation ive ever seen when he wants to. He is more spotty over the course of an entire 26 episode series though. Big mix of quality. From amazing to just good. But some things he gets real ambitious about which I love.
Like, Animatrix. He had 2 amazing shorts. Not a tough time schedule or asked for too much either. Just do a short story. So much quality is poured into these. Detective story was so cool being black and what as it was. The city looked stunning. Then the Kid's story where he did the whole thing in rough sketch form. So cool. Just really trying new stuff and I love that. Cowboy Bebop's movie meanwhile had kick ass animation to. Especially the music video where I think he just messed with how alive he could make everything look. Some of the best animation I've ever seen.
Anyway, as far as Champloo... Needs a villain and a long arc. Bebop never did that but you cant exactly recreate Bebop in a samurai universe. They also did have a recurring story with Spike and Vicious which included two 2 parters and an amazing episode. The interest in Bebop was the innovation and creativity in this future where the possibilities are endless for stories and adventures though. You could recreate detective like stories, mob stories, lone warrior, drug deals, casinos, ship battles, police stories, etc. Its a lot more complex. Samurai Champloo is cool but you can only take so much before it begins to get a bit boring. There's no character who comes on screen like Vicious or Pierrot Le Fou, and makes you open your eyes not wanting to miss a second, savoring every moment he's on screen.
All the locations also look very similar as is to be expected with a anime recreating a historical period. But you more emphasis on the differences between cities and towns. Bebop had a great thing to work with, planets. I was really interested in what Earth was like as well as Mars, Venus, etc.
