The Attack on Titan series had, in its inception, a great deal of thematic depth. The titans can be seen to represent sin, and particularly with Eren’s ability to become a titan, the idea of mankind as being the very monsters they fight has a lot to say about morality and humanity. Unfortunately, by volume six, the series has started to rely on that initial setup as a crutch, and fails to add new intrigue to the story.
The terrifying nature of mankind’s struggle has been well defined by the first three volumes of Attack on Titan. Now, the story takes a step back to look at the training they’ve all gone through, which unfortunately costs the narrative a good deal of momentum.
The people who preceded the coming of the titans thought that a non-human enemy would unite them. But to think so is to misunderstand the human condition – a fact Eren now understands far too well.
Forget everything you know about manga.
