I feel like some reviews either love One Piece to death or just hates it at most its most of the time gets a 10 or gets a 1 which I feel like as a manga One Piece is neither of those. It isn’t a Godsend of a Manga or such a trashy manga that is just straight poop. I will review One Piece as non-bias as I can but no promises. Spoiler Warning intensified.

Art (7/10) – For my own personal preference, I love One Piece’s style, but I know it isn’t the best around. The drawing are nice and easily looked at, with panels making you follow in accordance making it a breeze to read at times. But sometimes there are a tad bit too much happening at times that jokes and interactions can be miss. For as many manga as I read, One Piece art is not the best but It’s not the worst. Does your manga have to have a good art to tell a compelling story, if so tell ONE that his stories bad because his art is bad compared to something like berserk, which is of course false since those two tell two very different but compelling story also. Still of course I do find his creation of male character are fine and dandy compared to his female characters. I was sadden when Robin went from a nice tan to an almost Hancock look alike in the time skip(there was a concept art to give Robin short hair which I thought would have had made her stand out more compared to now but Oda probably wanted to save that for Koala). Also, almost most females are either babes, kids, old hags, or fat; most being the former. After time skip almost all the girl characters have giant boobs, which I don’t mind but was it necessary for every female.
Characters (7/10) – I do personally love all the characters in One Piece but know that they get little developments for such a long running series. Yes, most time the characters are one note at times and they feel like there are no development, but character wise they are all enjoyable and mesh well against each other. I do feel like with all the adventure they had there must be some growth in the characters. But like many stated before Oda likes to treat each arc as its own self contain story, which may be his downfall. They should all mesh together better which I felt he did well when the crew reach Shabody Archipelago. So many things happening but it felt like they all connected well compared to the other parts. Not saying that the other arcs and saga didn't bode well together, just not as well. But like many stated, Usopp could and should be braver with all the adventures they been through, Luffy less of a numbskull, etc. But how I feel about it is that the Strawhat crew is that they accept you for who you are no matter if you are weak or not. That is why Luffy after his fight with Aokiji felt he needed to get stronger because he knows he got weaker people in his crew. He knows if he doesn't get stronger, he will lose people on the way to finding One Piece and he doesn't want that. Usopp reaffirm that desire in their fight, because Usopp saying he feels like he will be thrown away one day for being weak, hurt Luffy deeply and made him find ways to be stronger. Same for Robin which I felt like had the most development as a character in the story, since for her trusting people wasn't a given. She has been targeted for years by the government and after being in the crew she was scared that the people she been so close with might turn their backs on her. After saving her from the world government Robin opened up even more toward the crew and became more relax than normal around them. Also, there are so many side characters that are use and reuse which I felt like other manga should do so more often. Like how Dragon that we met in the beginning and was a mysterious is being use more now and is a big player in the story. Or how like Luffy friend Coby didn’t just become a run of the mill Marine after they separated in the beginning but now is a Marine Captain. Plus another benefit is that I feel like all the characters gets growth and are use properly compared to other shonen series. For example, like in Naruto where beside team 7 did any of the other fan favorite characters matter in the last fight as much. Team 7 are fighting gods now and everyone else can’t really fight on par with them anymore. Or like in Dragon Ball where Saiyan’s is all there need now, characters like Picollo or Krillin are just there to fill in spots. While in One Piece the crew are given a role to do stuff and while not everyone is strong, they all got a power boost and are still very prevalent in the story. Which is why I feel like there is a need for Luffy to be an idiot because for that very reason his crew matters even more to the story and won’t just all of a sudden be him focus only.
Story (8/10)- Honestly, One Piece is my all-time favorite read but I can see the flaws in the story and how there are better stories out there. Yes, yes each arc is the same with Luffy them fighting a bad guy with a time limit with Luffy knocking out the bad guy saving the trouble island. Ends with a celebration and the crew leaves for a new island to get closer to Raftel. Which does sound boring when you put it that way anything would. But sometimes knowing the ending isn't a bad thing because we are here to find out how the characters will get to that point and what occur in the middle. Even if most of the arc are the same format, the adventures in those arcs are different. The world is change by Luffy and his crew but they aren't the only one that are causing all the changes. Blackbeard cause way more change to the world more than Luffy did. He did the impossible by having two devil fruit power, he killed White Beard(albeit it he was close to death already), he injured Shanks(but of course a sea king did also LOL), he cause the Summit War between Whitebeard and the Marine, and became a new Yonkou. He sounds way more dangerous than the most wanted man right now Dragon, but of course we barely know anything about Dragon himself. Which is another reason why I like the story in One Piece. There are so many mysteries still left in the story even after 900 chapters, which sounds stupid but it just makes it more enjoyable. Like who is Joyboy, what is the void century, when will Noah's ark be use, why will Luffy destroy Fishmen Island, and so forth. These don't take center stage at all and sometimes even be forgotten because the story is so long, but still they are a foreshadow of what to come. Also, the world building is great, even if it does feel like an LSD fuel world, but why is that a bad thing. It just makes the world way more unique in my mind.
On a personal note I give One Piece a solid 10 out of 10 for me, but for a manga review note One Piece is a 7.5. That may seem like it is a bit harsh but honestly it isn’t One Piece’s fault at all. It is how Manga are written faults, especially for long running shonen manga. Popular manga are kept as long as possible until their popularity falls down greatly before getting ax like Bleach or if it’s still popular enough it gets a proper send off like Naruto and Dragon Ball to only be brought back to be use as a cash cow again. Oda even stated that the series was to be concluded back in 2002 five years after he started on it and even written an ending for One Piece since then but of course the popularity demands it to continue. Which is why I felt like One Piece does a better job at this than most long running fight series, there are still mysteries, we seen the power ceiling with the Summit War but not all of it since White Beard was already an aging and sick man, and the adventure still feel fun but of course can be a tad bit to long at times in arcs. If anything One Piece is an enjoyable Manga, that isn’t a Godsend or shit manga. It doesn’t change the fabric of story telling but it doesn’t just straight bore you. Last thing I want to mention Overhyping something almost always kills most of the enjoyment of a story, which is did for me for Hunter X Hunter, which is why instead stop listening to other people opinion and just read One Piece as a manga not as the Giant titan it is but instead as any other regular stories out there.
