It’s a good show that stands on it’s own. Manga / anime adaptation or not, it succeeded by actually being an entertaining show.

I’m a casual One Piece manga fan and I would say it is probably the most faithful adaption to the source material. Most of the sets and scenes are bang on and the cast is just fantastic and likeable. Luffy, Zoro and Nami in particular are great casts and really grew on me. But most importantly the show has heart, which is something a lot of the modern show lacks and tries to substitute with paint-by-color beats.

100% worth watching and would recommend.
