This is one very interesting anime to watch...very entertaining. I like the way they adopted the "swashbuckling pirate" - genre of old and made an anime where we can relate to all the characters, whether they be villains or heroes.
Granted, the art and the storylines are mediocre to average at best (I mean, how many variations of "pirate stories" can you have?), but it's the very well-developed characters which draw you to this series. You can see each of the character's motivations, Luffy's ambition, Suron/Zorro's determination, Nami's cunning, Boo's hidden courage, and Sanji's sense of honor as a cook (whatever that is!)
Sure, with this much character development the episode count really soars, as it's on to the hundreds and still ongoing. But unlike the "marathoners" such as DBZ, you won't get bored with the pacing of this series and will want to watch all story arcs to their conclusion.
For ye other landlubbers out there...post your comments/rants/raves to this anime. Har har har!
