Fans of Cowboy Bebop, the animated space-western series, will find plenty to love in Samurai Champloo as they share the same creator and a lot of the same aesthetics. Although the space and samurai themes could not be anymore different, they are similar in other ways. The group of loners and rejects, the dramatic and cinematic styles, and a heavy influence of music are shared amongst both while still keeping their own individual and unique charm. Fans of either series should absolutely watch both shows.
Overall, I would recommend Samurai Champloo to people who are trying to get into animated Japanese shows or action cartoons in general as it really is considered a classic.
