Yeah, seems there were lots of flaws in the movie. And Luke really had an interesting idea that Brandt an Dupont can be both sense offenders. What's really cool here is that you guys noticed the background! How could you notice the people in the back? It was awesome!!! I wish I have those skills, because I didn't notice anything but main character.
Other flaw was after killing Dupont, John Preston came into a room where they control all the media in the city; where Dupont's head is floating in the screen, there people ran away immediately when they saw John Preston in blood and dead people. That shows that all of those people who worked there had emotion because they could feel "Scared".
I have had a same post as you, Jame about people looked emotional in this movie. 1. While John was meeting Father, Father behaved in angry by clapping the desk. 2. When the black man took John to Father and then, black man was arrested that he was looked like scared and nervous.
