I am not a fan of the Gantz manga and I have not even read it. I don't really read manga and comics. So when it comes to a live-action adaptation, I am clueless about the characters but I can make out with the adaptation's explanation or the adaptation may even prompt me to pick up the manga. Gantz as far as I know is famous for its over-the-top violence and nudity. I saw many criticisms on the adaptation saying that it lacks of blood and nudity. For a general movie-goer who does not know what to expect in the adaptation will find this a little bloody and will wish for some more nudity.

The story: There is a sick game which revives dead people and commands them to play along. Their tasks are to kill aliens. Aliens!!! Once an alien dies, the players are given points according to their contribution to the death of the alien. A number of points will reward that person. Gantz is touted as a big-budget action sci-fi movie. And yes, it is. The big action scenes especially the final one show that much money is spent. The aliens look okay but are unique in some ways. Characters wise is okay, some are a bit interesting but some are just there for sake of being there. The pace is decent for a Japanese movie, not to say that all Japanese movies are slow-paced. Watching this feels like watching the Japanese doing a Hollywood movie which is decently paced and features big action scenes. With the final movie completing this series, it will be expected to end with a cliffhanger.

Overall: It is good for a Japanese action movie, it could be one of the best I have seen. But for a character movie, it could have done better. It is worth a watch whether you are a Gantz fan or not. Since fans are saying that the manga has more violence and nudity, I am compelled to pick up the manga and to see if it is true. For a non-Gantz fan, I can't wait for part 2 which will conclude the movie series. Sadly, Singaporeans will have to wait.
