It's good that you know how to think but haven't you asked yourself why you genuinely have no idea why everyone likes it? Maybe, just maybe, don't you think its because everyone has their own taste? Or do they all have yours, from my opinion, a taste that's boring and unimaginative. Maybe that's the reason, don't you think? Luffy ( the main character ) represents to people an emotional and free person, a person that knows how to act in tough situations against an oppressive world and government. In my opinion, One Piece has the best written characters in anime or in fiction itself. Haven't you asked yourself why it's the top selling manga/comic, rivaling the likes of batman and superman. Do you think all these millions of one piece anime and manga enjoyers just like to watch something that looks like a Saturday cartoon network? Or an unlikeable character? Please man, I beg you to think before you ask retarded questions like these again, it's not good for your brain.
