Attack on Titan: Take the Support of Lie to Tell the Truth.

For any movie or series in order to be absolutely great, it should have a perfect story, plot, and theme. Story: it gives us a general sense of what the movie or series is all about. For example, the story Naruto is all about a boy who wants become Hokage. Plot: it is the most crucial part consisting world building, characters, and how the things gonna play out in the story. Theme: it basically gives us the genre and moral of the story. Attack on Titan is among the few shows which have aced all these three elements. However, Attack on Titan has a negative sensation among the viewers regarding the ending of the story in the manga. Many fans have criticized the harsh ending of the manga excepting it to be a happy and wholesome ending. But Attack on Titan was never meant for a feel-good or happy ending in the first place. The way this show explores human politics and war so deeply that it has already saturated its content relatively with the world it has created. And there can be only one perfect way to end the show which has already been done by its author Hajime Isayama.

Attack on Titan was never really about a boy fighting Titans to free humanity. It was the story of  Marleyans and Eldians and the war between them which was constantly foreshadowed from the start. The concept of war between Marleyans and Eldians is just like the ripple effect. Once the war is started by anyone clan it will go on forever. The only way to stop the war is to wipe both clans and finally achieve freedom. This explains the swing in Eren's character who wants to free humanity by killing every human. The way Eren approaches rumbling is what Hajime Isayama wants to show us take the support of lie to tell the truth. The following is from last year's interview with Shintaro Kawakubu ( Isayama's editor). During one part of the interview he quotes Isayama concerning the messages of the story:

"If I wanted to tell people that “you shouldn’t kill people”, it wouldn’t make sense to tell them directly that “you shouldn’t kill people”. Because the seven billion people in the world know that “people must not be killed”, and since the murders continue today, making a verbal warning is pointless. If that’s the case, then the words “It’s okay to kill people” might carry more weight if you just look at the result, because there’s a chance that the person hearing it will think “What are you talking about? The right thing to do is not to kill!” So if you have a message you want to convey, perhaps the right thing to do is not to draw it exactly as society expects it"

If I have to recommend someone a show about war then it would definitely be Attack on Titan. It has set up the bar of brilliance so high that it would take decades for other writers to come up with something grand like Attack on Titan. Many artists, creators, and writers will be inspired by this show something epic.
