Cowboy Bebop definately had one of the best openings of any show I've seen. Well designed and went with the music perfectly. Most other shows seem to just tape cutscenes together and work more like a music video than a real opener for the show. Bebop was original and well-designed, and worked well with the theme of the story as well as the soundtrack. Samurai Champloo was done by the same people, I believe, and follows in the same vein, but reversed the anachronisms found in bebop, and although I think it was an alright show, I don't think it did as good a job as the original.
