Before I start, let me tell you this; if you are planning to watch this anime, forget it! It`s not worth watching. I`m not saying that it`s that bad, no. But it is much better if you start this series with the manga.

GANTZ is extremely violent anime. If you are a fainthearted type of person, I suggest you stay away. You are dealing with a berry gory and sadistic anime here! And one more thing, this anime is not suitable for those under 18 years old; because of it`s nudity, and violence of course.

This anime ran for two season, and lasted for 26 episodes, ONLY! Here`s the reason why I don`t recommend this anime to you, the second season of this anime sucks. [SPOILER] The story of this anime were completely different from the manga after Kato`s death. I ended up reading the manga after watching this anime! I`m not satisfied with what they did with the anime. At least they should continue where the story is hanging.

A pair of high school students, Kei Kurono and Masaru Kato, are run over by a subway train in an attempt to save the life of a homeless drunk who had fallen onto the tracks. Following their deaths, Kurono and Kato find themselves transported to the interior of an unfurnished Tokyo apartment. The pair soon realize others are present and find that they are not able to leave the apartment. At one end of the room there is a featureless black sphere known as "Gantz".

After some time in the room, the Gantz sphere opens up, revealing a bald naked man with a breathing mask and wires attached to his head, and three racks protruding from it, that offer various items for them to use. These include the custom fitting black suits Gantz makes for each of them, giving them super-human abilities, a controller which acts as a radar and stealth unit, and three types of guns.
When the Gantz sphere opens, green text appears on its surface, informing those present that their "lives have ended and now belong" to him. A picture and brief information is shown of some of the Gantz Targets, Gantz ordering them to go and kill them. All but one target shown thus far, have been aliens living on Earth, which take on a wide variety of forms. After a period of time which varies between missions, everyone except Gantz are transported to the location of the mission.

Those sent cannot return from the mission until all enemies have been killed, or the time limit has run out. If they survive a successful mission, each individual is awarded points for the aliens they have killed. They are then allowed to leave, and live their lives as they see fit until Gantz summons them back again for the next mission. The only way to stop having to participate in the missions is to earn one hundred points, and choose the option to be freed. Several participants are killed through the third mission they are given, leaving Kurono as the only survivor and the new leader from the "Gantz Team". However, as the series continues, Kurono participates with the objective to revive his deceased friends with the 100 points he can obtain throughout the missions. After several missions, Gantz's sphere indicates that the human race will be over in a week for an unknown reason, but it also frees all the participants from the game.

The animation was just okay, the CG`s were great tho but they messed up at some part of the anime. You`ll know what I`m talking about IF you watch this anime. Story sucks compared to the manga.

Animation: 2/5
Story: 2/5
Enjoyment: 2/5

To tell you the truth, GANTZ is a very addictive series. I`m not really a manga fan myself, well I do follow a few manga but I`m more into anime. GANTZ is an exception. Like I told you earlier, GANTZ is very addictive. After you watch the anime, (where they left the story with a cliffhanger) it made you wanna know more about GANTZ`s world and all the mysteries in it. I`ve finish reading the latest chapter of the manga and can`t wait for the new one to be released.

GANTZ live-action movie
(two parter) was announced few moons ago. The movies will star Kazunari Ninomiya and Ken'ichi Matsuyama and will be directed by Shinsuke Sato. The movies will be released in the spring and winter of 2011.
