Thru their deaths by misfortune, various people are periodically recruited by a machine in the form of a dark sphere called "Gantz"(I'm guessing it's completely random since an old lady and a kid were also conscripted). At the center of all this are 3 young people: 2 guys and a girl. The 2 guys, Kel and Kato, have a history but hadn't seen each other in a while. Kel is at first timid, and even cowardly but later sees himself as heroic. Kato is intense and shudders and grimaces a lot (killed his father and went to juvie). The girl is a real cute "girly girl" who panics and runs away a lot. She's got the hots for Kato who doesn't notice or care cause he's too busy grimacing and thinking about other people.
A very decent movie with a nice concept but marred mainly by one annoying fact: Time and time again one of these people had an opportunity to shoot the threat and did not do it. Or did (eventually), but then instead of firing again, and again ----and again, if necessary, until said threat was demolished they just stood around with their mouth open wasting time until the threat recovered to attack again (Man, was that annoying!!!). If that won't get under your skin too much and you like sci-fi, I recommend this. Love, Boloxxxi.
