Synopsis
By most accounts, Kei Kurono is a selfish jerk, which makes it all the more interesting when he dies trying to save a stranger from a subway train. Instead of whatever afterlife he expected, he wakes up in a bare apartment with a bunch of other dead people and a giant black sphere called Gantz. The sphere gives them weapons, skintight suits, and a simple order: go kill aliens hiding in Tokyo. If they refuse, they die again, for real this time. This 13-episode TV series from Gonzo leans hard into its seinen roots. It's dark, violent, and genuinely unsettling in ways that go beyond just the gore. The real tension comes from watching ordinary people, most of them confused, scared, and completely unprepared: get thrown into impossible situations where hesitation gets you killed. Kei and his childhood friend Kato handle it in completely different ways, and that contrast drives a lot of the emotional weight. The blend of CGI and traditional animation gives the action scenes a distinct, slightly surreal look that fits the tone perfectly, and the soundtrack keeps everything feeling tense even in the quieter moments. If you liked Deadman Wonderland's high-stakes survival or Btooom!'s death-game premise but want something that leans more into psychological dread and moral ambiguity, Gantz is right in that lane. Just know going in: it doesn't pull punches, and it's not trying to make you comfortable.

Liked it until that last 2 episodes
i liked the premise is like a battle royal with people that had dead, the human way that, how the protagonist see the live and how is himself contrast with the archetype of the typical badass protagonist as well of the other protagonists
What a great ending for an overall pretty bad season. The pacing and action were great in this episode. It was fantastic to see Kurono actually lock in and be likable for once during the battle against the bird. It closed the season out nicely.
This episode had much better pacing, as things actually happened in this episode instead of characters just yelling at each other. However, it still could've been a bit more action-focused. The ending for some of the characters is quite emotional.
Kato is the best. Even though he hesitates to shoot, he still manages to help and be the coolest guy around! The pacing is slow once again, so it's a bit boring. However, the emotion at the end of this episode, as well as Kato being amazing as always, makes it worth the watch.
Another slow one. This is very skippable since nothing happens. The fight is boring, the other characters talking is boring; nothing gets done at all beside Nishi getting himself into trouble. Him saying he'll never apologize adds to his character, but even so, he's not likable.
I was hoping the action would start again, but this one has a lot of standing around and talking again. It is intense, as the different factions within the group start to turn on each other, but it was still slow overall until the last few minutes.
Finally almost back to the action. Some of the scenes were brutal, and it's interesting seeing the characters we already know having to interact with the new Gantz players and try to explain what's happening. It's slow again, but important to watch because of what's to come.
While this episode is still slow, we get more insight about Kato's life. His character is the only thing making this show worth watching for me. It's interesting getting to see his school life, as well as his less-than-optimal home life as well.
Definite skip, even for first-time watchers. There was so many erotic, unnecessary scenes and it makes it a very uncomfortable watch. It's also very slow on top of that, so it's really just a waste of 23 minutes of your time when you could be watching something better.
This episode had a few cool animation moments, like the door closing, however the pacing was very slow. We learn more about the characters' lives outside the game which helps develop why they are the way they are. It's important for first-time watchers so they can understand.
This episode is important for first-time watchers as it gives a lot of exposition and better explains what is happening. However, the pacing is very slow due to all the talking and standing around. The mystery of what Gantz really is remains, but that just adds to the suspense.
This episode gives a better insight into Kei's personality and how he's changed since his childhood. It helps develop him a lot and makes him a more likable protagonist. Also, the fight scenes were pretty cool despite the pretty primitive animation.
Unfolds like an inevitable breakdown. A brief sense of victory gives way to something harsher. Kurono doesn’t retreat; he adjusts. And in a system built on chaos, that shift matters. It isn’t heroic, it’s reactive. But it’s enough to change the outcome.
Plays like a controlled unraveling. The split isn’t just tactical; it exposes how fragile the group really is. Coordination slips, gear fails, and the threat grows faster than they can react. What feels routine turns into a trap. Control here is temporary, and it fades fast.
Feels like a breaking point. Chaos isn’t just spectacle; it exposes who these people really are. Kato hesitates, Kurono adapts, and Nishi pays the price. The pacing stays tight, but it’s the weight of consequence that lingers. Survival here always comes with a cost.
This episode feels rough in places, but tension still holds. Nishi’s downfall hits hard, and Kato stepping up adds weight. Not the strongest episode, but the pressure and character moments keep it watchable.
Ramps up tension before the fight even starts. The group falls apart, trust breaks, and chaos takes over. Pacing feels tight and uneasy, with pressure building fast. It’s less about action, more about how people crack, and that makes it hit harder. Music is impressive, though.
Mixes quiet choices with sudden chaos. New faces drop in fast, tension spikes, and the mood stays uneasy. The pacing builds toward the next mission while relationships shift under pressure. Not flashy, but the stakes rise quickly, and one mistake could change everything.
Trades action for grounded tension. Kato steps up, Kurono stays unsure, and Kishimoto’s reality hits harder. The pacing is calm but heavy, focusing on character growth and real-world pressure. Not explosive, but the buildup deepens the stakes in a subtle way.
