Death does not have to be the end; one can live again, but only through beating the game posed by the black ball called Gantz.

On his way home to celebrate his younger brother's birthday, brave and kind-hearted student named Masaru Katou is stabbed to death. He awakes in a small room with a cityscape view in the heart of Tokyo—and he is not alone. To his surprise, it is not the afterlife, but the waiting room for a high stakes game with their lives on the line. Before he has the chance to process the situation, Masaru is handed a gun and teleported into the center of Osaka to carry out one simple task: eliminate any alien on sight.

Accompanied by the aged Yoshikazu Suzuki, the stunning idol Reika Shimohira, and the cold but experienced Jouichirou Nishi, Masaru must overcome his fears in order to survive the game and return home to his waiting brother.

Watched at Toho Cinema, Tokyo.

While Gantz O follows the Osaka Arc it makes some big changes, ones you can see the reason for and some you can't.

Rated at PG12 in Japan, the drug abusing Kyo Hanaki and Rapist Kazuo Kuwabara are absent, understandable.

Less understandable is that most of the Tokyo team are abscent too, it's faster to say the only ones shown are Kurono, Suzuki, Reika, Nishi & Kato....I'm so sad that Host Samurai was absent.

The movie also incorporates an alternative end to the Oni Arc that starts the film off, which was so awesome it gave me goosebumps.

The CGI is amazing and despite it ...

Mixed Feelings
Basically, if you don't know anything about Gantz, I'd say don't bother. The movie clearly tries to introduce newcomers to the Gantz game concept but does so in such an awkward and incomplete way that I'd say it's very hard to understand unless you're at least kind of familiar with the rules.

The story makes some drastic changes from the manga, which by themselves wouldn't make it bad, but together make the Osaka Arc a much simpler and more boring experience (You can feel this in particular during the first half of the movie). The new ending is the only change I think affected the movie ...

Gantz-O takes place in Osaka, Japan, while it is under attack by various and violent monsters who kill indiscriminately. The people fighting these monsters are common civilian plucked from near death by GANTZ, a mysterious black orb inside an apartment. After the rules of this “game” set up by the orb are clumsily explained by the other characters, our protagonist Katou is whisked away on his first mission.
In Osaka besieged by chaos, the group will attempt to survive as best they can by relying on their own strength. Unfortunately, this strength does not amount to much and as such only Katou takes charge to face ...
