A perfectly serviceable anime might ruin its well-earned goodwill with a particularly disappointing or shocking ending. Death Note suffers from this problem, as its brilliant cat-and-mouse build-up feels upended by a rushed resolution that is significantly different from the manga.
At other times, abstract or confusing endings can leave audiences feeling dissatisfied, as is the case with the “Congratulations!” final scene in the original Neon Genesis Evangelion . While this anime ending has its thematic merits, fan reactions remain split, especially when contextualized against the fleshed-out conclusions of The End of Evangelion and the Rebuild tetralogy .
While anime with well-received endings (like Fullmetal Alchemist: Brotherhood or Mob Psycho 100 ) are not immune to constructive criticism, such discourse rarely sparks heated debates. Conversely, the majority might be inclined to agree that a series like The Promised Neverland wasted its potential with a notoriously lackluster ending.
With these distinctions in mind, here are five anime with endings that are considered controversial and hotly debated, with reactions ranging from mixed to split right down the middle.

This leads to an abrupt conclusion that isn’t given enough time to breathe after a satisfying buildup. What’s more, Satoru’s final confrontation with antagonist Gaku Yashiro is supposed to be a pivotal moment that feels rather underwhelming in the adaptation. The final episode ostensibly delivers an abbreviated version of the source material, so we lose out on key context, motivations, and backstory that could enrich what’s happening on-screen. One might argue that Erased retains its emotional core until the end, but a sudden pivot to heavy-handed reveals cheapens what could’ve been a brilliant conclusion.
Hajime Isayama’s dark fantasy shonen grapples with complex morality and how it can change someone like Eren Yeager, who starts as a hero worth rooting for in Attack on Titan . The manga’s extended ending fixes most of the criticisms levied at the original conclusion, but sentiments are decidedly mixed when it comes to the Attack on Titan anime. Although breathtaking in its adaptation of the uncompromising final chapter, the ending introduces a drastic change to Eren’s motivations, which retroactively alters how we perceive the story as a whole.
For some, such a shocking heel turn works, giving the sprawling saga a radical, if bittersweet perspective. On the…
