Manga (and novels) that had disappointing anime adaptations (according to me). Series that only had piecemeal "greatest hits" OVAs will also be included. Series that fell off after a promising debut are also included. Series with one good adaptation but some bad ones are also included.

[muttering real quiet so people can choose to pretend they didn't hear me] chainsaw man...


I'm sorry, I am going to pretend I didn't hear that. I've read up to what the anime adapts and I think it's pretty great. 😅 I could understand why you'd think so, though!!
[whispering so so sooo softly] i just think mappa was a poor choice [walking towards a cave] for a manga with the breakneck pacing of ren & stimpy [the cave mouth swallows me] to be turned into prestige television™ [barely audible now] when it could've gone to trigger [speaking at a frequency only bats can hear] or at least had someone like kai ikarashi in charge [i fall into the earth's core and dissolve]
I’m gonna drop my nominations of Soul Eater (the world’s most mediocre ending 🤢), Deadman Wonderland and Gantz. Disappointment city all around 🫣


Those ones are notorious!! I hadn't seen them for myself so I didn't want to add them, but they should definitely go on the list.
The Tokyo ghoul anime might be the adaptation that filled me with the most rage I ever had the displeasure of watching, the rage I felt when watching it was immense 😂 It had some opening and endings that were great, so I guess I have to thank it for introducing me to amazarashi at least


The music was so good for such a mid series!!
They needed something to not make you close the episode immediately 😭
omg promised neverland....

you are so real for this list
Okay 1997 Berserk, worth it. Anything that came out after that, we don’t talk about it. 😬


Yeah, I liked the OVA but even from small clips the TV show looked like ass. 💀
I hadn't seen the Uzumaki anime adaptation yet. That's too bad about that one!
I remember seeing a live action adaptation years ago that was quite different and not the best, though it feels nostalgic these days 🤭


Yeah, it pretty notoriously just... ran out of budget partially through, and they decided to just put it out anyway. The first episode or two are a pretty good adaptation, though!
