One of the most disappointing experiences one can have as an anime fan is encountering a show with a good premise but bad execution. The summaries sound great; the first few episodes are fun, but eventually, you realize certain anime programs just don't hold up.
For example, Moyashimon has a cool premise, but the show makes Tadayasu's ability to talk to microbes pretty underwhelming. And while the characters in Sword Art Online get trapped in a virtual reality that's super advanced, the female heroine is reduced to a glorified damsel in distress. Both shows have great potential, but they fall short.
It's not like viewers can't enjoy these anime after realizing the shows don't live up to their potential, but it's hard to think about them without getting at least a little upset. Let's commiserate!
Premise: When Masamune Makabe asks out his crush, Aki Adagaki, he's turned down in the most humiliating way possible. To get revenge, he loses a ton of weight and changes his image in the hopes of winning her affection - with the intention of dumping her right back.
Why It Tanked: Not only does Masamune never get his revenge, he also never specifically decides to forgo it. Instead, the story peters out into oblivion, ending with a school play in which nothing is actually resolved. The show has some great moments, particularly when Masamune reflects on how his history of being bullied has impacted his self-esteem, but those moments are fleeting. The central conflict is never resolved, new characters crop up at the last minute and add nothing to the overall story, and the whole thing falls flat. Could this be resolved with a second season? Sure - but so far, there's no sign that one is forthcoming.
Premise: Thousands of people are trapped in a virtual reality game called Sword Art Online. To escape and get back to their lives, they must clear the game - but the catch is, if they die in-game, they also die in real life.
Why It Tanked: Sword Art Online can't be said to have failed entirely - it's a wildly popular show, and it had some truly great moments. But what could have been a great show turned into one with some serious flaws that are hard to overlook. Kirito's personality is bland and poorly developed. There's a harem setup that isn't capitalized on, frustrating both viewers who don't enjoy harem anime at all, and viewers who like it and want to the trope used effectively. Asuna, who starts off as a strong hero, is reduced to a damsel in distress by the end of the first series. Kirito's sister (technically his cousin, but raised as his sister) turns out to be in love with him, blasting fans with an incestuous sub plot out of nowhere. That's a lot of flaws for 50 episodes.
Premise: God abandons humanity, so no one can be born, and no one can die. Characters who already faced death continue to endure in a zombie-like existence. A group known as Grave Keepers are tasked with putting the dead to rest.
Why It Tanked: Rather than explore the unique premise, Sunday Without God opts for multiple disconnected arcs that have little to do with each other or the show as a whole. The anime focuses on a school instead of the real meat - anime zombies.
Premise: In a setting that vaguely resembles Ireland, technology so advanced the average person no longer has to work or struggle for survival. However, things are not as simple and idyllic as they appear.
Why It Tanked: After setting up a lush and beautiful world that seems ripe for exploring, the series just falls short. The romance subplot isn't very interesting and most of the characters are lackluster and forgettable. Plus, most of the mysteries of the Fractale System remain unexplained. The world is ambitious and scenic, but that's it.
In fact, the artist responsible for the original manga, claimed the televised version was boring.
