The Most Disappointing Anime Sequels According to Fans

In a recent debate on a popular commentary forum dedicated to anime, fans have expressed their opinions on which anime should never have had a sequel, whether in the form of a second season or a movie. This lively exchange of opinions has generated a large number of varied and passionate responses from the community.

Forum participants have highlighted several reasons why they feel some sequels might be disappointing for fans. One of the most common arguments is that the sequel lacks the charm and originality that made the series popular in the first place. In many cases, fans feel that the story had already reached its climax in the original season and that a sequel only dilutes the quality of the plot or explores unnecessary territories.

Additionally, some fans have expressed their displeasure with sequels that seem to be created primarily for commercial purposes, rather than having a strong and meaningful narrative. This can lead to the feeling that the sequel lacks soul and feels like a mere attempt to capitalize on the success of the original anime.

Another important point discussed on the forum is how a poorly executed sequel can damage the perception of the series as a whole. If the quality of animation, direction, or character development decreases in the sequel, this can negatively affect the image of the franchise as a whole and leave fans with a sense of disappointment and frustration.

"The first season of Yakusaku no Neverland was amazing and even though I haven't read the manga, I've heard it's a good adaptation. The second season, however, was not. Translating from manga to anime aside, overall it was a disaster and didn't make much sense. According to readers of the manga, it also skipped one of the manga's best arcs and character developments. So if you're interested, I recommend you watch the first season and skip the second, better read the manga."
"Eureka Seven AO. At first I was excited, but as I progressed I became more and more disappointed. All of E7's follow-up projects are hell-bent on shitting on it for points of tragedy for some reason and it's very irritating."
"The only one that was a real disappointment was Yakusuko no Neverland, because that first season set the bar very high I think. For me all the seasons of DanMachi have not been bad, but I didn't have fun watching them and they always seemed like a bummer to me, I think in this case I have changed my tastes since the seasons didn't seem really bad to me. I watched the second season, but dropped out the third season when I told myself I wasn't having much fun. I felt more like I was watching it because I had fun with the first one."
"Tokyo Ghoul Root A, it completely deviated from the manga. The pacing and writing of the characters fell apart. If I'm not mistaken, the animation studio ignored the author's wishes and took the liberties they wanted. The result was one of the worst masterpieces ever adapted from manga."
"Dagashi Kashi. Last year I watched the first season and I really liked the characters and getting to know the different Dagashi. I tried to watch the second season, but I didn't like it at all. I think reducing the length of the episodes was a bad idea. Also, I also don't like the fact that one of the main characters is pretty much missing until the final episode. I should also mention that I prefer the art style of the first season to that of the second, even though the art style of the second season is more faithful to the manga."
"Terra Formars".
"Berserk of 2016".
"The second part of the second season of Re:ZERO. Snail rhythm, dialogues that made others feel sorry, some cringe moments, I didn't care about the vast majority of the backstories, either because I found them boring or just plain bad, plus the characters that made it didn't matter to me that much."
"I wasn't interested in the second or third season of DanMachi."
"I've never liked the second season of Code Geass. At first it has its peak, but from episode 8 onwards everything is a mess. Just because he finishes well doesn't mean he gets a pass."
"The second part of the second season of Tensei shitara Slime Datta Ken. It was like Game of Thrones, but if GoT had shitty dialogue and it was extremely boring."
"Not all season, but the final arc of Mob Psycho 100 season 2 was disappointing to me."
"Megalo Box. I just couldn't enjoy the second season and I still think it was unnecessary."
"One of the most recent ones for me was HameFura, which I quite enjoyed with the first season, but I felt like the sequel was going off track and losing most of what I had liked about it."
"I'm Standing on 1000000 Lives, season two. I thought the first season was good, but the dialogue was terrible and convoluted second season."
"Nanatsu no Taizai season 3. I'll never forget what they did to my boys Escanor and Meliodas..."
"Since others said the worst, here are some honorable mentions: Shokugaki no Soma S5 and Yakusoku no Neverland S2."
"Aldnoah.Zero Season 2".
"Index Season 3. It almost made me quit the Toaru series."
"I show my age here, but... GUNDAM SEED DESTINY. The original Gundam Seed is easily an 8 or 9/10. Destiny barely qualifies as a 2/10 and it's mostly because of the killer soundtrack that keeps it afloat."
