I’m not as well versed in a lot of manga as some others here, and I damn sure am not familiar with most Japanese writers outside of the comic book industry, but even though he’s probably in the top ten, the back half of his story is so disjointed and ridiculous that I don’t think it’s fair to say he’s the greatest ever. The problem with Oda is that he WAS an incredible writer before he started introducing a ton of secondary characters with no evident purpose, manufacturing tension by dragging several arcs out way longer than necessary instead of letting the story itself drive the drama, and cutting corners by removing a lot of what made the first half of OP such an endearing, appealing product in the first place. If we’re going to judge him by his best work, then yeah, he’s one of the GOATs; if we judge him by ALL of his work, he drops more than a few places on that list.
