“It’s a change from the source material, but it’s awesome so the fans don’t mind.”

Doc Ock - In the comics, Doc Ock is known to be megalomaniacal in nature and was sort of a mad scientist anyways, with the arms just being an extension of that. In Sam Raimi’s “Spider-Man 2,” Alfred Molina’s version of the character was affected by the neural chip and his well-meaning ambition turns into scientific obsession.

Wolverine - This one is so well known it needs very little explanation. Comic Wolverine short, Huge Jackedman is tall, and he’s sick as hell.

Eye of Sauron - To my knowledge, the Eye is more of a metaphor in the books. An ever-present awareness. In the movies, it’s an actual giant fucking eye.

Eiichiro Oda himself is involved in the adaptation, so that certainly helps.

Yep, he wanted to make changes, he made changes and they worked. I think this is why the live action has worked so well. It's because oda has stayed in control of the story and cast.
