The Preachiness Is Too Much For Me
Let me start this post by stating that as far as morality goes, there is no black and white, only different shades of gray. And in case someone wants to throw out some outlandish hypothetical scenario, ("What if someone burns down your house, murders your entire family, and then cuts your arm off and leaves you in the desert to die FOR NO REASON!!!"), I'll elaborate one step further. There is no moral issue worth making a movie about that is completely black and white.
The reason that these issues are not completely black and white is that we all see ourselves as the heroes of our own story. Even the most diabolical villains have reasoning to back up their ideas, and in their minds, the pros of their actions outweigh the cons.
Now let's extend this idea to The Visitor, where the good guys want immigration reform and the bad guys want to keep immigration laws constant. First of all, immigration is objectively a very split issue in this country, with many intriguing arguments both for and against reform. But if your only knowledge on the subject was this movie, is that the idea you would get?
From about the 30 minute mark of the movie, (Tarek's arrest), the audience is barraged with scene after scene of immigrants being abused, deported, and completely dehumanized without a single line of dialogue even attempting to defend the actions of the immigration officers. There isn't a character on the "bad guy" side of the argument who is given more than a handful of lines of dialogue, and those lines are mostly limited to something to the effect of "Please step away from the window, Sir."
It might not have been so bad if you got the sense that the immigration officers were at least fairly decent people outside of their jobs, but Tom McCarthy can't even grace us with that. The absolute worst part of this movie for me was when the waiter at the cafe by the holding cell makes an offhand comment about how the immigration officers don't tip. It's such a cheap shot, completely unnecessary and has nothing to do with the message of the movie.
You don't gain respect for a boxer by watching him hit a punching bag for a few minutes. You gain respect for him when you see him go toe to toe with a formidable opponent and knock him out in the tenth round. The villains of The Visitor fall way too far on the punching bag side of this analogy, and the movie really suffers as a result.
