One quality that makes anime so rewarding is following the way it builds momentum. A good anime comes with a great premise, then delivers striking characters and just enough mystery to keep everyone watching, weaving events together toward a finale that ties it all up. Great endings stick with fans because they feel like a rewarding payoff.
The anime answers lingering questions and resolves rivalries, basically giving the viewer the feeling that their time was respected. However, when an anime stumbles at the finish line, the damage is real. All that buildup goes to waste, and fans feel betrayed. These anime are painful reminders of shows that started as favorites until their endings changed everything.
Food Wars!: Shokugeki no Soma
Food Wars is one of the rare cooking anime that manages to be both ridiculously over-the-top and still informative about food. While it aired, viewers followed Soma Yukihira as he climbed the culinary ladder, always outdoing established chefs with his talent.
The early arcs showed off Soma’s growth and his rivals’ depth, turning the anime into an underwhelming show that felt like an intense battle shōnen disguised as a cooking show. However, the story's premise felt watered down as subsequent arcs progressed.
The BLUE tournament, which had great potential, was completely rushed. The anime lost much of the tension and creativity it had at the beginning, and ended with character arcs wrapped up too neatly and entire plot developments glossed over.
Tengen Toppa Gurren Lagann
Simon is widely regarded as one of the best examples of a character who transforms from a timid underdog into a true leader. For most of Tengen Toppa Gurren Lagann, fans were sucked into the anime’s mecha battles filled with unrelenting energy and heart.
The first half saw Simon awakening to his role as a leader, while the second half featured battles that showcased significant displays of power and potential. Unfortunately, the ending left everyone conflicted.
After defeating the Anti-Spiral, Simon simply walked away and gave up Nia, who disappeared after their wedding. It was bittersweet, but ineffectively so, as it provided no real closure and felt like a fade-out that didn’t match the story that preceded it.
InuYasha
Inuyasha is known for being a gateway anime of the 2000s, with its mix of feudal Japan fantasy and romance. It lasted for years, and many fans remained loyal to it, drawn in by Kagome’s travels and Inuyasha’s inner struggles.
The anime had a solid setup, which involved collecting shards of the Shikon Jewel while navigating rivalries and love triangles. What damaged the story was the pacing; episodes dragged on, and arcs looped endlessly.
By the time the end finally came, many fans were not only dissatisfied but also exhausted. Even when Inuyasha: The Final Act came around, it only provided a rushed story that didn’t have the emotional weight it could have.
KADO: The Right Answer
While Koujirou Shindou is introduced as a competent negotiator in KADO: The Right Answer, his role quickly escalates when a massive cube lands on Earth. The early episodes promised a rare and thoughtful exploration of diplomacy and humanity's readiness to handle the godlike knowledge at their fingertips.
The anime’s approach to science fiction was fresh and intelligent until it lost focus. In the final stretch, it became more clichéd, with Shindou fighting a battle that was so at odds with everything prior. The ending felt like elements were introduced solely to wrap up the story quickly, and a great deal of potential was wasted in the process.
Wonder Egg Priority
In earlier episodes, Wonder Egg Priority looked like it was destined to become one of anime’s next major darlings. The anime featured dreamlike visuals and a nuanced understanding of its sensitive subjects. It was brave and full of emotion, showing how Ai Ooto saved girls from real trauma. The stories had topics like loneliness, bullying, and suicide handled with care.
Eventually, the show’s ambition grew beyond what it could handle. It became bogged down in confusing exposition and backstories, leaving characters with unresolved arcs. Instead of satisfaction, the anime left fans with uncertainty, disappointment, and a general feeling of unease. What was once a tear-jerking anime ultimately left them hanging.
Kuma Miko: Girl Meets Bear
On the other side of cozy slice-of-life anime lies Kuma Miko: Girl Meets Bear, which opens as a lighthearted comedy starring Machi and her talking bear guardian, Natsu. The anime appears whimsical and fun, appealing to viewers who like rural settings and coming-of-age stories.
The anime promised that Machi would grow into independence and pursue her dreams in the city. Unfortunately, instead of building on Machi’s growth throughout the anime, it showed her as incapable of handling life in the city. Her regression into someone entirely dependent on Natsu was uncomfortable to watch, killing the anime’s heartwarming and empowering effect.
Gantz
What worked for Gantz initially was its unpredictability. Kei Kurono and others are caught in the Gantz room and must hunt an alien with no guarantee of safety. Characters were killed off without hesitation, and the creatures were dark and grotesque.
Even though the primary missions built tension and added shock value, the anime began inserting fillers and rushing developments, creating an abrupt and meaningless ending. Letting everything reset at the end rendered all the death and struggle that had come before vain. Gantz ended in a way that suggested that the creators simply tired out.
Darling in the Franxx
Darling in the Franxx was another anime that began with intrigue, only to let all of that fade away. It mixed action and coming-of-age drama in a way that immediately grabbed attention.
The anime began by setting up mysteries and showcasing the unusual way children piloted mechs in pairs. The anime inspired much speculation, with viewers thinking that some grand sci-fi revelation was forthcoming. Instead, the plot took a turn towards alien invaders and unraveling character arcs.
What had initially been healthy tension grew into melodrama, and side characters slowly grew sidelined until they became clichés. Darling in the Franxx turned romance and mystery into a textbook case of wasted buildup.
The Promised Neverland
Ray, Norman, and Emma are yet to escape the minds of fans who were captivated by The Promised Neverland’s first season. The anime began with one of the best debuts. The characters were great, and the pacing was just right. Unfortunately, the following season marked the beginning of doom for the anime.
Instead of slowly building the outside world and the demon society, The Promised Neverland skipped arcs and condensed several chapters from the manga into a sprint. The plot twists weren’t set up well enough to be truly surprising or impactful. It seemed as though the anime was intentionally undoing all its good parts and throwing away its strongest material.
Soul Eater
Fans haven't been shy when voicing frustration about how Soul Eater ended. While it aired, the anime was packed with style and energy. The characters were lively, and the arcs with Medusa and Asura were incredibly thrilling. With a unique blend of action and comedy, it was easy for Soul Eater to stand out in the late 2000s anime landscape.
However, for the finale, instead of a climactic battle fought with teamwork, Maka ended it all with a bit of courage. It was a simplistic, almost laughable resolution to the story compared to the complex buildup that came at the start.
