Onepiece is a life. It teaches us how friendship is greater than everything as well as the hurdles you will face in your life. The plot, the characters (zoroooo luv you) and the animation everything is fine ( like zoro). There is a statement in the anime community basically in onepiece fandom that you should watch onepiece before you complete your life on earth and it's true ( I know there are people who don't like this genre) but atleast to know the story wouldn't create any loss. Everyone try this and see how much it will make you happy!
