You guys clearly know little about animation & manga. One Piece is the most popular in every single country except America. The English dub of One Piece is HORRIBLE, which is why it is a lot less popular. It never caught on. It's the only country it's happened in.
The manga is excellent & the anime is pretty good, but the manga is so much better in story than both of those. It is a lot more emotional and engaging. The characters are excellent and the story is very interesting without being overly complicated like Bleach or silly like Naruto. Naruto is practically dumbed down and I just don't understand anyone who still likes it....I feel like they need to grow out of it. It's for babies.
I wish more people would give One Piece a chance. It's excellent.
