This phenomenon demonstrates that even the most renowned works are not immune to criticism. Understandings and interpretations of story conclusions can vary significantly among viewers.
Ultimately, the discourse on this Japanese forum underscores the pivotal role of the conclusion in the overall perception of an anime, and the quality of the finale can be a determining factor in how viewers assess the entire work.

Here are some opinions from netizens:
- In my opinion, Lycoris Recoil and The Idolmaster: Cinderella Girls have the worst endings.
- Speaking of this, I would mention Mobile Suit Gundam: The Witch from Mercury.
- Don't forget Wonder Egg!
- We can't ignore the ending of Wonder Egg Priority; it's truly dreadful. The story was intriguing until halfway, but I had to abandon it because it seemed like it wouldn't have a deserving conclusion, and it turned out that way.
- When it comes to the worst endings, Hoshiai no Sora and Meganebu! come to mind for me.
- How did Zombieland Saga season two end? Don't announce a show and then forget about it!
- For me, it's Zombieland Saga. I think the entire second season is inferior to the first.
- I'm sure I'll mention GANTZ.
- In my opinion, Zatch Bell! deserves to be added to this list.
- Back Arrow had a terribly unsatisfying ending. I think Gorō Taniguchi is living off past glory.
- Megaton Musashi, despite my best efforts to watch the second season, it never got any better.
- Mahou Sensou, no doubt about it.
- I nominate Kamisama ni Natta Hi and Mahou Shoujo Madoka Magica.
- I'm sure Uma Musume: Pretty Derby's second season belongs here.
- I think Neon Genesis Evangelion should be on this list. I know it's a beloved series, but if you have to add a few more films to explain the ending, you didn't do it right from the start.
- Personally, I'm not satisfied with the ending of Rebuild of Evangelion, but I have to mention that everything turned sour in the third film.
- Lycoris Recoil should also be included here.
- I want to mention Babylon, a surprising misstep from Nozaki Mado, the scriptwriter of Kado: The Right Answer. I believe the production of a 12-episode series with such rich source material is utterly pointless and seems like the production process was calling it quits poorly.
- Code Geass: Hangyaku no Lelouch, even though everything seemed to end well, I think the plot and the main character's death were poorly executed.
