I've just recently got into this series and I must say it is quite interesting. However, it seems to be a 'childish One Peice' - not necessarily a bad thing but I hope that the story gets more cultivating.
The manga is considerably better than the anime in my opinion, but this seems to be common with most series since it is an adaptation. I've watched the first 10 episodes and I'm not too impressed if I must say, maybe i'm used to series like Naruto etc where things are serious from the very beginning etc.. hmm I'll keep my eye on this one.
