Story >>>
The story of this anime is what really amazes me , the final objective is to become the pirate king that may leave you to think this will be the same old same old like beating pirate crews etc but if you think like that then you have another thing coming as the story of One Piece is deep & the focus on each character & their story is good.
Animation >>>
The animation is good & gives a really nice action adventure feel to the series , due to the art style used it may lack a bit of seriousness at times that you would get in many anime with dark style of animation like one seen in Full Metal Alchemist , but this was the best style for the series & i can't see any other style of animation working well for the series
Sound >>>
I Love the sound in One Piece , especially the specific themes that build you up for the moment , like the Overtaken theme that lead you up to big fights & Run Away theme when Luffy manages to escape from the enemy swiftly
Characters >>>
Not all anime show importance of each person no matter how lame you think he may be , One Piece Assigns roles to each characters who also have their dreams or ambitions to fulfill as their story progresses , even the minor characters that you think will go away in some time will have a major part to play in the story , you will like even those weird looking characters & be touched emotionally if something bad happens to them
Enjoyment >>>
I Really enjoyed watching this anime so much that at times i think man how awesome it would be if i was was alive back a few centuries ago & roam the sea with my friends instead of robbing people , this new take on pirates is simply awesome
Final Verdict >>>
This anime series is what makes your anime experience complete you simply can't miss this series.
