Best thing I ever watched/read/seen in my life. And trust me I've seen a lot from Indian cinema to Hollywood, but there's nothing as legendary as One Piece. It is the most special thing in my life. It is a book so good you just can't stop reading. It's more addictive than cocaine and I literally mean it. It helped me through tough times, there isn't a chapter for which I HAVEN'T SMILED. Every single page is more intense than any american TV show. (That includes Breaking Bad.)
Art: Oda's art, duh. 10/10
Story: The greatest story mankind has ever come up with. 10/10
Character: Every character is close to my heart, every One Piece fan at this situation should be biased, cause they are the greatest fictional characters. 10/10
Enjoyment: The greatest form of entertainment a living creature can ever witness. One Piece is a true treasure. 10/10
Overall: The greatest manga of all time, the best fictional universe of all time, the most beautiful treasure.
Thank you, Oda sensei.
