Story: 5
The show has a good premise and some pretty cool situations, but it is poorly executed, in my opinion. The fight scenes feel like something out of Naruto or DBZ: long and drawn out. The story could have been told much more quickly, and its a bit disappointing that such a cool premise wasn't taken advantage of as much as it could be. There could have been more games than just two per season, instead of having all the characters standing in front of the enemy about to pull the trigger but chickening out most of the time.
Either way it was pretty good until the infamous last episode... which was filled with boring and stupid dialogue and not the kind of action you would hope to have in the final episode... and then a completely meaningless ending.
Art: 7
The art was pretty good, and the 3D effect was unique and interesting despite the few times in which it looks ugly, as if it was rendered in 3D and the characters are just flat plains facing the camera (which it probably was). But I think they did a good job on the animation besides those parts.
Sound: 6
The sound was good especially the completely freaky monster voices. Besides that it wasn't too memorable except that it fit well. The music is sometimes ugly and sounds like it was a MIDI file.
The music at the beginning is cool, though.
Character: 6
Besides the three main characters, the rest were completely flat. They were more charactures instead of characters, although that seemed to be the point. Gantz did a great job making completely unsympathetic and people (except for a few) to populate the anime besides the three main characters, showing how evil the human race is. In this part, the show excels, since these were never meant to be developed at all and instead just meant to show how awful some people can be.
The problem with the show's characters are the main ones. Although Kei was a pretty complex character that you can both love and hate and laugh at at the same time, the other two were just annoying. Kei was a fun character, though. At first he is not very easy to like but by the end he is likable and cool. His extreme perversion was funny and lit up an otherwise bleak and brutal anime.
Enjoyment: 4
This is the part that annoys me. It could have been really enjoyable with all the cool fight scenes but it just ended up being tedious and painful. In some parts, it was meant to be that way, like the episodes in-between the games, and it was ok because they are meant to show humandkind's evil, but the fight scenes shouldn't have also been painful. I don't like listing to lengthy discussions in the middle of a battle when everything has paused just to hear them speak predictable and repetitive things, or see flashbacks over and over. I also found myself screaming at them to just shoot already. If you want something more enjoyable, read the manga.
Overall: 5
Gantz is an anime that is genius in some places and just plain stupid in others, plus its just too drawn out. I would only suggest this to fans of the manga or for someone with extreme patience or someone who is planning to do something while watching it. Near the end of the anime I was browsing the web and stuff while watching it because it was just too boring.
I wouldn't suggest it to those who are looking just for gore and violence either because the rest of the show is just too tedious if thats all you are looking for.
I don't regret watching it, though, it just could have been done much better.
