It's really rough, language wise, the character type and just general feel of the show. It's not gentle at all. It's dark and gets intense pretty quickly.
Lots of blood, gore and violence which is part of why I enjoyed it, but other people may not. It's not just little bits, it's pretty in your face stuff. So if you're touchy with those kinds of things, it could be best to avoid it, but on the other hand if you're like me and love that stuff, I'm sure you'll love Gantz.
Kei Kuruno suddenly and very unexpectedly finds an old friend, Masaru Katou. They end up in a room with strangers sitting, waiting to see if anybody else appears from a big black ball in the center of the room. Which sounds crazy, and it is.
The two friends then end up being the ones to look after Kei Kishimoto whom also appears out of nowhere.
They suddenly find themselves in a strange killing game, but not of the normal kind.
The plot is interesting and unusual. It's not fast paced or slow, it floats around the middle. Though with that being the case, it keeps you interested since you're learning what's going on along the way.
The characters can be a little frustrating, going from being scared to strong and confident and then dropping back again.
(The kid especially drove me nuts)
Overall it is enjoyable. If you like different, sci-fi mixed with supernatural and lots of blood and guts. It was worth watching and I'll definitely continue to the second season.
