Attack on Titan is an absolute masterpiece. I say that with no hesitancy, and with no doubt. Its story is so masterfully crafted from start to finish, each story beat perfectly referencing every story element that came before it, that it remains unparalleled by any other series. It has overtaken every other series on my list of greatest anime & manga of all time, particularly for having one of the most profound, meaningful, emotional, philosophical, psychological, topical, diverse, epic, disturbing, impactful, interesting, cohesive, deliberate, inventive, and flawless stories ever conceived. It addresses and comments on an insane variety of deep & controversial topics - everything ranging from nihilism, religion, & xenophobia to historical alteration, governmental corruption & international diplomacy - and asks all the right questions regarding everything worth thinking about, from the purpose of life & our shared human flaws to ambiguous morality & what it means to live. All of this is presented via a powerful cast whom all go through substantial & meaningful character development throughout, acting as the perfect set of eyes to perceive these events as they unfold and to appreciate the ingenious delivery of the story as a whole.

You're in for one hell of a mind-blowing ride, so sit back, take in all the little details with the incredibly expansive world-building, and enjoy the unforgettable experience of a lifetime.
