==========================================
Fun aside, but this is mostly what this anime felt like. It's not that it's bad at all (the story is quite interesting and offers great potential to make this show an awesome anime), but there's still so much that made me feel uncomfortable watching this show. But let's start with the good thing:
Story:
The main characters die in the very beginning and get kinda reborn in an appartment in Tokyo. They receive some super cool weapons and a suit, that offers superhuman strength, as well as the mission to use this equipment to kill some aliens, that are hiding in town, within 60 minutes. Why they got to do that remains unexplained, but I didn't mind that.
That actually seemed to be a pretty cool concept to me, and I did enjoy the first episodes.
Characters:
The characters are cheap... like... really cheap. We got the generic loser, that fell for a beautiful girl, we got the generic beautiful girl, that fell for a tall, muscular guy, and we got the generic muscular guy, that's not interested in the girl at all. Besides that we have a lot of annoying side characters, that are mainly used to be crushed by some aliens. Also there's no bit of character development in the course of the anime, which would be necessary to make the characters even a little more interesting. So long story short: The characters aren't really bad, but they're also far from being special or at least interesting.
Animation/Artstyle/etc:
The anime looks alright, no more, no less, a 5 out of 10, the least you could expect but nothing better. I'm really struggling how to describe what the show looks like, but I think "alright" just describes it perfectly well. There's a lot of splatter and a lot of nudity; fans will like it, others won't. The design of the aliens is alright aswell (an onion-frakenstein's monster-hybrid and birds without wings). Nothing to get excited about, but they're okay.
Sound:
The soundtrack is actually pretty good. It fits the whole scenario and accompanies the action scenes as well as the not-so-action-scenes. The opening's still stuck in my head right now by the way.
Enjoyment:
First of all I did enjoy most parts of the show, because I like the idea and the way the story is told. BUT! Now we get to the big minus, that made some of the episodes a pain in the ass: The fighting scenes are sooo drawn out. I heard a few people comparing it to Dragonball Z, but Gantz is completely different (in a bad way). In DBZ both the hero and the villain stop fighting for hours just to talk about how much they hate each other, but at least they're as fair not to attack their enemy while he's still talking. In Gantz the "heroes" stop fighting to do nothing, while the aliens keep crushing them. It sometimes felt like they didn't even want to kill these monsters, and I personally really do hate that. It even made me fast forward some scenes because I just couldn't handle it, and eventually it's the reason I rate this anime not as good as I'd actually like to.
Recommandation:
Don't watch it if you can't see blood. Don't watch it if you don't like sex scenes. Don't watch it if you get worked up over characters standing on the sidelines. Watch it if you're into sci-fi/aliens/mystery/superpowers/whatsoever, and you'll be having a good time.
