Which anime adaptation of a manga is the most accurate?

Well, One Piece is another example. The anime largely adheres to the manga's storyline, although there might be some filler episodes. But the core plot points are accurately represented.

I think Death Note has a very accurate manga adaptation. The anime follows the manga closely, keeping the same plot and character developments.

I'd say Attack on Titan has a quite precise manga adaptation. The animation brings the intense action and complex storylines of the manga to life with great fidelity. Although there might be some artistic variations, the essence is well-preserved.

I'd say 'Naruto' has a pretty accurate manga adaptation. It keeps the main storylines and character developments intact. There are a few fillers and minor alterations, but it doesn't deviate too much from the manga.

It's hard to say for sure. But 'One Piece' has an anime adaptation that's pretty close to the manga, although there are some differences in the pacing and filler episodes.

I think One Piece has a very accurate manga adaptation. The anime captures the essence and major plot points of the manga quite well.

I'd say 'Naruto' has a quite accurate manga adaptation. The anime captures the essence of the manga well, and although there are some fillers, the main story arcs are followed closely.

I'd say 'Fullmetal Alchemist: Brotherhood' has one of the most accurate manga adaptations. It follows the manga closely, keeping all the key plot points and character developments intact.

'Naruto' is another anime that has a reasonably accurate manga adaptation. It manages to capture the key moments and character developments from the manga. Although there are a few filler episodes, the main storyline follows the manga closely.

I think 'Fullmetal Alchemist: Brotherhood' has one of the most accurate manga adaptations. The plot, characters, and key moments are closely replicated.
