David Ayer seems to misunderstand his own character
While listening to the DVD commentary for the Harsh Times, I noticed that David Ayer, the writer/director, seems to have trouble with character identification. He gives contradictory information about the inner workings of Jim's mind. I do think it was clever how Ayer establishes that Jim uses different social masks, or personas, around the people in his life. However, there is a moment in the commentary when Ayer explains that Jim enjoys violence and even enjoys killing other people. This does not fit in with what was established as the character's identity. How does that fit into Jim having intense nightmares of murder and mayhem on the battle field? You don't have nightmares about something that you enjoy doing. Ayer seems to not understand his own character. We all have behaviors that we are prone to. Jim is someone who is prone to violent behavior. He has lived a life surrounded by violence and has taken part in violence but that does not mean that he enjoys violence. God knows that there are quiet a few behaviors that I'm prone to that I'm not proud of. Everyone does. Problem is that Jim's are more destructive than most.
Think about the scene where Jim and Mike watch that guy get his throat cut in the bar. Jim's initial reaction was not excitement or enjoyment. For a moment, he was frozen in place and looked disturbed. Almost as though he was transported back to a memory from Iraq. As soon as he and Mike reached the car though then Jim had put back up his bad ass persona that pretends isn't fazed by anything. Jim tries to play it cool. Until Jim is reminded of a friend of his from the war that had his arms and legs blown off. While talking about his friend he begins to lower his guard and show that he isn't as unfazed by violence as he likes others to think.
In the film, it is set up that Jim wants nothing more than to get a steady job in LA and to settle down with his woman. He doesn't really begin to psychologically break down until his violent past catches up with him when he's asked to go to Columbia to continue a life of violence. Did he look happy when he got the job? No. Again, his behavior is prone to a life of violence so he took the job. But on a deeper level it's not the life he wanted. He felt trapped at that point. He was already unstable and on the edge as it was but being denied the life he wanted with Marta and on top of that returning to the very thing that has been haunting him in his dreams pushes him all the way off the deep end. It seems that this is a very important aspect that a director should understand about his character and I think it's odd that Ayer didn't think about it on that level.
