Samurai Champloo is a one of those shows were you don't have to see every episode and the first few episodes you'll be think is there any reason behind the story. However there are some very funny moments some involving accurate history details with some very completely non relevant items that don't fit the the time period.
That said the main characters are very good Mugan I swear is borrowed from the samurai in Lupin the third. The artwork is amazing and overall you will find enjoyment from in most of the episodes as samurai manga/animes goes its not the best you'll find but has a style all of its own.
You will find yourself liking the main characters and wish the story had more relevance rather than the weak story line that guides the story to an ok ending. So to sum up the artwork is good the story is poor for the most part but is worth watching.
