Some thoughts on why spectators hate the kid
First of all I have to clarify: I was one of the people who liked the movie and found the kid awfully annoying at first. I've done some introspection and rewatching to determine why I found him so annoying and whether his annoying behavior was a negative aspect of the film or central to the meaning of it. I’ll try to be brief: first I provide some introspection on why we found the kid so annoying, and second I give some thoughts on why we shouldn’t hate him given that his attitude is pretty much the point of the movie.
The first question: Why do we hate the kid? The reason, to me, is obvious: because we empathize more with the father. We imagine ourselves in his position: knowing you can’t trust anybody and live in the worst world possible, always thinking of survival and never being able to let your guard down. The father is the only reason why they really survive at all. Given this, we imagine ourselves being the ones responsible for guaranteeing the survival of the “group” so to speak, and find the kid continuingly thwarting the father’s efforts, not because the kid intentionally does so but because he’s extremely naïve (such as giving food to people who would have left them for dead). We, as spectators, find him as a liability for survival, but the father’s only reason for surviving is taking care of his son. Summing up, I believe that we, as spectators, empathize more with the father’s struggle for survival than we do for his unconditional love for his son, given that the son is pretty naïve and complicates things.
The second question: should we “hate” the kid for being a handicap for surviving? I believe this is the hardest part to reflect upon. Given the first answer, we know we empathize with the father on his struggle for survival and find that the kid makes it harder to survive in the worst world possible. But the kid’s innocence is what pretty much gives meaning to the film; it’s the last piece of human kindness and belief of helping others left in the world. Facing the end of mankind, there’s no room for kindness or “nice gestures”: nobody who has managed to survive this long has done so by giving food to those who are starving, everyone’s hands are dirty, including the father’s. So the kid being annoying, naïve, thwarting survival attempts, giving food to people who would have left them for dead and so on represents the last remnant of one of the most distinctive characteristics of mankind that can’t be described in a short word, but I would use “innocence”.
Summing up, I’ve given some thoughts on why we hate(d) the kid and that him being annoying is pretty much the point of the movie. Of course there are multiple aspects of the film that are worthy of attention (and I mean, multiple), I’ve just shared some thoughts on one point which many posts are continuously referring to. Anyway I’ve liked the film very much and hope this might shed some light on the movie’s theme.
