Whenever I pick up a really good manga series, I immediately try to see if their is an anime to go with it. Almost all the series I’ve read were lucky enough to have been made into one like Sailor Moon, Revolutionary Girl Utena, Fushigi Yugi, Ceres: Celestial Legend, Cardcaptor Sakura, and the list goes on.
I think a lot of the animes made around the 90’s like the ones I have mentioned above have been good adaptations of their original source material. It is to be expected that an anime that’s based off of the manga will be somewhat faithful to the series, but then veer off and become a slightly different version of its original. Most of these changes are not bad at all. It just makes the anime kind of like its own story separate from the manga. The same happens when books are made into films. They are just going to be completely different from the other despite every intention of being faithful to the original. Things have to get cut out or they add things to the film based on what looks better on the screen. Some things translate better in a book than in film and vice versa.
