What is great about the anime One Piece

One Piece is personally one of my favorite anime.
One piece is an adventurous anime about the strawhat pirates. They travel from island to island fighting the marines or other pirates in an attempt to become the pirate king.

One Piece uses its many episodes to develop its ever increasing cast of characters and keeps many of they relevant even after the arc they were introduced. For example buggy was one of the first villains and still managed to be an important at the impel down arc and marineford arc. This is probably because of the authors planning in advance.

One piece is written quite extraordinary with foreshadowing characters and events. All the main arcs seem to have a life lesson hidden within them. The author is good with creatively adding new powers and abilities .

Although one piece isn't perfect the good out way the bad. One piece may be a little slow in the beginning, one piece is a great anime and would recommend.

Even many of the filler arcs are interesting like the g8 filler arc.

Comment on what I should post next? Should I review specific arcs of One Piece? Should I review new episodes of anime that come out? Or review different anime?
