I just watched The 6th Day and was pleasantly surprised. However, I'm not 100% sure about the ending. Which Arnie goes to Argentina? The clone? Or the real Arnie who thinks he's the clone? I ask because the one going to Argentina has a perfect DNA profile, while clones are supposed to have in-built genetic defects. So did the clone not tell the real Arnie the truth and then had him sent off to Argentina with the belief that he's the clone? Any comments?
