Hiroya Oku’s long running manga series Gantz has already been adapted as a TV anime as well as two very successful live action films from Shinsuke Sato. Gantz:O (ガンツ:オー) is the first feature length animated treatment of the series and makes use of 3D CGI and motion capture for a hyperrealistic approach to alien killing action. “O” for Osaka rather than “0” for zero, the movie is inspired by the spin-off Osaka arc of the manga shifting the action south from the regular setting of central Tokyo.
Kicking off in Shibuya, the first scene features the demise of the franchise’s protagonist, Kei Kurono (Yuki Kaji), as he defeats one of the giant monsters terrorising the city and saves his friends but fails to save himself. A quick geographical cut takes us Osaka where there are reports of another disturbance, but the major threat turns out to be a depressingly commonplace one as a lone madman goes on a stabbing spree at a Tokyo train station.
17 year old high school student Masaru Kato (Daisuke Ono) gets himself mixed up in the incident when he ignores the crowds of people running in the opposite direction and comes to the aid of an injured old man. Sadly, Kato is repeatedly stabbed by the attacker and “dies” at the scene only to be resurrected in front of Gantz. Introduced to fellow players Suzuki (Shuuichi Ikeda) – an old man who “died” of a stroke, Reika (Saori Hayami) – an idol who was “killed” in a car crash, and the sardonic teenager Nishi (Tomohiro Kaku), Kato learns that he’s been given a second chance at life as a warrior in Gantz’s survival game in which he must fight off huge monsters within the time limit or die for real.
The entirety of Gantz:O revolves around this one climactic battle in the Osaka streets as Kato, Suzuki, Reika, and Nishi come into contact with the much more successful (but definitely less “nice”) Osaka detachment as backup in the fight against these fearsome monsters. As such, the main draw is furious action filled with bizarre scenes of carnage as the gang take down a collection of strange creatures often inspired by traditional folklore such as the huge winged tengu or shapeshifting priest-like boss. The visuals are extremely impressive displaying extreme fluidity of motion almost akin to live action photography.
Aesthetics are the key as the movie’s other elements are more or less inconsequential. As a bonus episode in the Gantz world, this is only to be expected and O makes no real attempt to do anything other than focus on the monster killing action. Thus character development is often shallow or non-existent, falling into genre clichés of cool heroes and depressed, brokenhearted women.
The question of self preservation vs altruism is central to the Gantz universe which begins from a position of nihilism and narcissistic self determination but gradually opens up to the importance of protecting one’s comrades, friends, family, and fellow human beings. Kato is the selfless hero the gang have been awaiting – his “death” results directly from his reckless attempt to help an injured person and his instinct is always to help those in need no matter the personal cost. His determination to save the lives of strangers is directly contrasted with his responsibility to the younger brother who is entirely dependent on him and would be lost should Kato lose his life. The film is ambivalent towards this dilemma as it constantly harks back to the people waiting for these secret warriors to come home, at once critical of them for risking their lives and acknowledging the fact that someone has to fight these monsters or everyone will die.
Despite the exposition heavy opening, Gantz:O does little to explain its world to the uninitiated and provides no logical explanations for its machinations leaving newcomers to the franchise with a host of unanswered questions but then all Gantz really wants to do is sell the message of altruism whilst destroying odd looking monsters in various bloody ways. Depressingly sexist, if edging away from the franchise’s nihilistic baseline, Gantz:O is an impressive visual spectacle but remains an essentially hollow, inconsequential addition to the Gantz canon.
