YMMV / One Piece – Marineford Arc

• Magnificent Bastard: Sengoku the Buddha is the most brilliant of the Marine Admirals. The top Fleet Admiral of Marineford, Sengoku leads the execution of Portgas D. Ace, revealing to the world that Ace is the son of Gol D. Roger, the former Pirate King. With the arrival of Ace's captain, "Whitebeard" Edward Newgate, Sengoku reveals a major trap for Whitebeard, sapping the morale of his forces with a carefully planned lie, trapping the pirates and closing in Marine forces, turning a near loss into a total rout for the strongest man alive with his own cunning.
• Padding: The arc has many chapters that consists of Luffy just running and fighting across the icy ground of Marineford trying to reach the platform where Ace is being held prisoner. It's a lot worse in the anime due to the adaptation's infamously slower pacing by this point in the series.
• Tough Act to Follow: The combination of its epic scale, Darker and Edgier tone, emotional depth and sheer Wham Episode factor made it one of if not the most acclaimed arcs by the fans, and every arc since has been judged as a result.
• Unintentionally Unsympathetic: Ace. This arc reveals that he went after Blackbeard against Whitebeard's orders, not on them as was the original implication, because he couldn't stand that Blackbeard had disgraced their father by betraying the crew like that. This got him captured by the World Government and prompted a full scale war between them and the Whitebeard Pirates to save him, while he angsts because they're doing all of this for him. And when he was finally freed after no small amount of bloodshed, he stops escaping because Akainu has insulted Whitebeard. Despite his allies, including Luffy of all people, pleading with him to ignore the jibes, he fights the admiral and is killed by him. It can be difficult to feel terribly sorry for him when not only did he disregard the sacrifice of the dozens if not hundreds of his allies that died for his sake, he got himself killed in a glaring case of Idiot Ball, rendering all their efforts pointless.
