I was watching the Live Action film of Gantz and noticed that it seems weird that after firing, the effects of a shot fired from a Gantz weapon is slow to occur, e.g.,
when the players who killed the Child Onion Alien attack the Adult Onion Alien, the Adult Alien shields himself with one of the players with each shot but it takes several seconds before the player's body explodes
when fighting the Buddhist Statue Aliens, there is a part where Kei shoots a limb of one of them (I think the giant one that Kannon deployed) which was going to punch him into the ground. Even after shooting it, the alien's fist continues to come toward Kei and if the delay had been longer, he could have been crushed
To me, this seems like a design flaw in the guns as it appears that the target of the shot can still move and possibly attack before it feels the effects of the attack and more so, the aliens seems to be able to react in real-time to the attacks (e.g., the Adult Onion Alien and Kannon shielding itself with its swords the moment Kei shoots).
So if the aliens can react in real-time to shots fired by Gantz Weapons, why is there a delay to the effects of such shots?
