This movie (THX 1138) is actually full of symbolism. But there's this part, almost at the beginning when THX 1138 is watching some holograms after the sexual one, about someone being hit by a robot.
Why is he watching this violence? I thought it might represent our inner impulse of rage and violence seeking we calm by watching violent movies or playing videogames, but I'm not sure, could it just be a warning?
He seems to be OK and even enjoy the sight of that brutality. Anyone knows for sure what they tried to represent here?
