The Transition:
Manga to Anime
How does one observe the differences between an anime and the manga from which it came? First of all, what is there too look for? In the case of an anime as Attack on Titan, I did not begin reading the manga until after watching the series on television. In the case of most fans, this is common, merely because no one really has the patience to wait a year and a half for a new season continuation. Putting that matter aside, I will simply compare what I personally observed about the manga versus the anime.
To begin simply, the most noticeable difference would have to be the artwork. Of course, a change in artists from manga to anime is very common (and for Attack on Titan a very much appreciated improvement). Hajime Isayama, the author and illustrator of the original Attack on Titan handed the rights of the manga to Wit Studio. This studio is what one might call "the disciple" of Studio I.G., which has given birth to numerous anime blockbusters in the past. This very fact, of course, gives some credibility to the young studio. Compliments especially go to the animators of the scenes involving equipment known as 3D Maneuvering Devices (example to the bottom left).
