Unplug and smash whatever device you're typing from and walk two miles south.
Seriously, one piece isn't for kids, these words shouldn't be spoken unless you've actually seen the series, and properly, otherwise what you're burgeoning makes you seem like a pedantic individual. If you think using children as slaves, and implanting a symbol on their backs as children with a heated iron rod, selling humans, treating them as dogs, not literally, Doflamingo pimping bishes. And so it goes on, childish? go outside and breathe in the fresh air and try typing that again. And moreover, those who've watched One piece, I've barely found anyone who's seen the series from end to finish and left a negative feedback (obviously, there are some, but that's rarely an occurrence, from my experience)
Judging a book from its cover are we? Or by its literal art work? Please.
