Reception

Critical response

Hand Shakers received largely negative critical reception upon its release, with reviewers highlighting its ambitious but flawed execution. On IMDb, the series holds an average rating of 3.3 out of 10 based on 10,235 user ratings (as of November 2025). Similarly, it scores 5.23 out of 10 on MyAnimeList from 43,483 users, reflecting widespread dissatisfaction. Anime News Network's community ratings averaged 4.024 out of 10, categorizing it as "not really good," with a median assessment of "weak." Critics praised the series' unique premise centered on "Hand Shakers"—partners who form bonds by clasping hands to summon weapons in a parallel dimension— for its innovative take on action and interpersonal dynamics. However, the narrative was frequently criticized for its convoluted plot, inconsistent pacing, and underdeveloped characters, which undermined the potential of the partnership theme. Anime News Network described it as "mystifying, maddening, and bizarre," bad in nearly every aspect, including storytelling that failed to capitalize on its conceptual intrigue. Otaku USA Magazine criticized the action sequences as unintelligible and choppy but faulted the overall substance, calling it a stylistic excess without meaningful depth. The series' legacy includes the 2019 sequel series , which some reviewers acknowledged as an improvement in narrative clarity and character focus, though it still received mixed responses with a score of 5.53 out of 10 (scored by 8,155 users as of November 2025). While Hand Shakers' bold visual innovations in were occasionally commended for their complexity, they could not salvage the broader critical consensus of underachievement.

Visual style and health concerns

The visual style of Hand Shakers, produced by the studio , is characterized by a distinctive aesthetic featuring heavy integration of computer-generated () elements with traditional animation, rapid editing sequences, and vibrant, oversaturated color palettes that often distort the imagery for dramatic effect. This approach includes frequent use of shaky camera movements, quick cuts, and mismatched frame rates between characters and backgrounds, creating a sense of visual disconnection that aims to heighten intensity during action scenes set in the virtual realm of . Critics noted that these techniques, while ambitious, resulted in jerky motion and unnatural panning that overwhelmed viewers, contributing to the series' polarizing reception. A major controversy surrounding the series stemmed from widespread viewer reports of and induced by its frenetic visuals, particularly in the premiere where shaky cam and abrupt distortions were most pronounced. Numerous fans and reviewers described experiencing headaches, , and physical discomfort, attributing it to the relentless camera simulation and high-speed editing that mimicked disorienting real-world motion. Post-airing discussions on forums and review sites highlighted these issues, with some viewers unable to continue watching beyond the initial episodes due to the adverse effects. Although no formal advisories were issued by broadcasters, the complaints were significant enough to prompt online warnings from communities, advising sensitive audiences to proceed with caution or avoid the series altogether. This visual methodology aligns with GoHands' signature style seen in prior works like K Project, where similar rapid cuts, CG-heavy environments, and stylized distortions were employed to evoke a sense of otherworldly immersion, though Hand Shakers amplified these elements to an extent that amplified the negative physiological responses. In K Project, such techniques were often praised for their striking, innovative look, but in Hand Shakers, the intensified application—combined with poorer execution in CG blending—led to criticism that the style prioritized artistic experimentation over viewer comfort. The result was a series that, while visually bold, became infamous for its potential to cause real health concerns among audiences.
