I dunno if it looked more real. But it sounded more real! Which in turn made it more real. I mean the way the guy screamed! I wonder if the y put a gun to the head of the voice actor and just said "scream for me."
It even got me to feel hurt when I saw it. It was almost like watching real war footage. And yeah, I also started to feel sorry for the machines, but in the end the machines did what humans did too, that is enslave humans. So I don't really care for them anymore.
Yeah, the two must disturbing scenes in 2nd reneisance was when they beat up and shot that robot woman in part 1 and then the battle in part 2 with the guy getting ripped out. Quite depressing....
