Ex-Arm is Still Crunchyroll’s Worst Anime

October 19, 2025

When Crunchyroll first began producing original anime, fans were excited to see what new stories would come from one of the most influential streaming platforms in anime history. Unfortunately, one particular show quickly derailed that optimism. Ex-Arm, which premiered in 2021, was supposed to be a bold, cyberpunk-inspired series. Instead, it became infamous for all the wrong reasons.

Four years later, Ex-Arm is still remembered as a spectacular failure anime so disastrously executed that fans have all but scrubbed it from collective memory. Despite being based on a well-received manga, the adaptation’s technical flaws, bizarre creative choices, and lack of direction made it nearly unwatchable. To this day, it stands as Crunchyroll’s most embarrassing misstep.

When a Cyberpunk Dream Became a CGI Nightmare

Ex-Arm had all the ingredients for success with a futuristic Tokyo, AI warfare, and a high-stakes plot centered on a boy who becomes a weaponized brain. But instead of sleek visuals and tight pacing, viewers were met with lifeless CGI and stilted animation that felt decades behind. The art style looked more like a student demo reel than a professional production.

The 3D animation wasn’t just bad, it clashed painfully with the 2D backdrops and static character models. Movements were jerky, faces barely emoted, and action scenes lost all sense of impact. The disjointed presentation made it impossible to take the story seriously, turning what could’ve been a thrilling cyberpunk mystery into unintentional comedy.

Even seasoned anime fans struggled to sit through the first episode. Social media quickly lit up with memes mocking its absurd visuals and awkward voice acting. What should’ve been a showcase of Crunchyroll’s original programming turned into a case study of how not to make anime.

Ex-Arm is a Cautionary Tale for the Streaming Era

Part of Ex-Arm’s failure stemmed from inexperience. The project was reportedly led by a director with no prior anime background and produced by a team unfamiliar with 3D animation workflows. That lack of expertise showed in every frame. It wasn’t just bad, it was glaringly unfinished, like a beta test accidentally released to the public.

The show’s disaster underscored the growing pains of Western companies trying to enter anime production. Crunchyroll had lofty ambitions to stand shoulder to shoulder with Japan’s top studios, but Ex-Arm proved that throwing money at a project isn’t enough. Vision, direction, and understanding of the medium matter far more than flashy tech.

In the years since, Crunchyroll has bounced back with genuinely strong originals like Tower of God and Fena: Pirate Princess. Yet Ex-Arm remains the black mark that fans can’t quite forget or, more accurately, choose not to remember. It stands as the ultimate reminder that not every anime adaptation deserves to be seen, no matter how advanced its technology claims to be.
