On his way to a job interview university student Kei Kurono (Kazunari Ninomiya) sees an old school friend, Masaru Kato (Kenichi Matsuyama), attempting to rescue a man who has fallen onto the subway tracks. After attempting to pull his friend back up onto the platform the two of them are hit by a train and killed, but instead of everything going dark, they wake up in a bright apartment room with a view of Tokyo Tower. There are several other people in the room, as well as a mysterious black orb. The orb, known as Gantz, tells them that they are dead, and their lives are now his to command. He orders them on various missions to kill aliens, handing out weapons and suits that give them super-human strength and speed. Kurono and Kato, alongside a girl named Kishimoto (Natsuna), and the others who have found themselves in the room are sent to various locations to destroy the aliens, and awarded points for their performances. Prizes are awarded for certain amounts of points, the most sought after being the chance to return to life.
Based on the popular manga by Hiroya Oku, “Gantz” is a great example of a beautifully simple mystery. Everything that is happening is made explicit, but without ever really explaining why it is happening. The central conceit, that the protagonists are dead already, leads to a surprising amount of tension, as you root for them to be returned to their lives, or discover what is going on with Gantz and the room. Excellent costume design and special effects make this an enjoyable watch and the action scenes are highly entertaining spectacles. The main criticisms I would have of the film is that it leaves a lot for the audience to piece together on very little information. Either you will learn to accept that what is going on is intended to be a fun, enjoyable action film, with an inexplicable plot; or it will seem as though the writer didn’t know how to tie up this fantastic mystery he had set up. There are huge amounts of gore and violence in the film, with bodies exploding, and deaths aplenty. The film is the first of two-parts, so you could see this more as a set-up explaining the basics of the world, and get you hooked into the bizarre world of Gantz.
There are some interesting ideas at play here. The first time you see the players transported to the Gantz room, it is intriguing enough to carry almost the entire film, as you keep watching to find out how they explain such an odd occurrence. The notion that there are hidden aliens, and the constant niggling suspicions around who or what the aliens are, whether the players are really alive or dead, are engaging. One of the most interesting ideas presented, though not particularly dwelt upon, is the notion that perhaps the aliens are not the bad guys after all, and the players are being tricked into killing innocent beings. Overall an enjoyable watch, though it spends more time on the action scenes and less on the philosophy or morality of what’s happening.
