The good about it:
There are many things Gantz does well. To begin with, it has a very interesting story. In the first episode, the mc dies along with other characters and has to kill some aliens to go back to his life. Sounds weird? Probably. But it's epic. Another thing is the music and art. The opening, the ending and the music put in some scenes are really great and suit the anime perfectly. The art style is a little bit weird but in my opinion is very good and graphic. Very gory too
The bad about it:
One thing Gantz fails in my opinion, is the characters. There are some awesome characters (like the MC -although a lot of people hate him, well I love him xD) but others are just not interesting and you really don't care much if they live or die.

If you like gore anime with good story, good action scenes and with a good pace then Gantz is definitely for you. Be warned that there is some nudity but, if you don't mind it, then it's also for you. Also, I think the second season is even better than the first one, and the manga beats both.
Hope you give this anime a chance despite the mixed reviews it has.
