Terminator 2 is a careful meditation on how much we can sympathise with a mashine. If Arnodls Terminator just looked like the metal skeleton the whole movie, we would not care one bit when he is melting in the steel. But the metal skeleton is what he is. Only for the fact that he looks human, even though everybody konws very clearly that he is a robot, we suddenly sympathise with him. I think that is interesting.
