I'm iffy about mangas and books in general. The people who read the book/manga are furious when something in the movie or anime is changed. Like the Hunger Games for example. Every person I asked who read the book first hated it. Then there are times when they leave out details like in Dangan Ronpa so the people who originally read the manga base their ratings by comparing the two. I like to stick to one thing to avoid the feeling of anger or disappointment when something is changed.
