Yes this has plot holes, but it is still thought-provoking.

Rating: 8/10 (23 March 2019)

Okay so I noticed that everyone is bashing on the "plot holes" that the movie contains which is fair enough. But there are certain aspects that are explained that people are overlooking or simply didn't catch.
For example, people keep asking how and why the tethered decided to kill their doppelgÃ¤ngers in the world above and how they knew where they were. It is alluded to that they are exact CLONES. They have a linked thought process. The only difference is that the tethered don't have souls because it couldn't be replicated. It is also clearly stated that the U.S. government created them to control the world above and abandoned them because they were flawed. So, this is an American epidemic, not a global one.
I have to mention that the acting was great from everyone and all of the performances were believable. Peele's usage of foreshadowing and symbolism was definitely admirable and not too predictable. But, I do have to acknowledge some of the plot holes that were not explained. Some of the big ones were obviously, where the hell did they get their outfits and gold scissors? How did the armed forces not decimate the tethered with superior weapons and knowledge? Why didn't the real Adelaide openly talk about the switch that occurred in the living room scene? I agree, that was all very stupid and unexplained.
But, all things considered the movie has so many great messages about society that can be interpreted in different ways. From what I gathered, the main messages were... if you suppress who you really are inside for too long, it's just going to fester and manifest itself in reality as a monster, so be who you really are because we all have a dark side. Also, the whole hands across America thing that people are bashing was kind of cool. He is trying to send the message that hate in the U.S. brings about unity amongst us which is obviously screwed up because it should be the opposite. Lastly, the whole bit with the dad being jealous of his rich friends was reinforcing the point that he is middle class and is still unappreciative of his situation. Then you get a brief glimpse at the rich friends and they are horrible people that are alcoholics, miserable, hate each other, and are superficial. The point is we should all see each other as people and the division of classes is getting worse and will eventually lead to a disaster. I have to leave off by saying I absolutely hate when movies implement any political agenda but Peele gets his message across subtly enough where it isn't annoying and is actually creative and thought provoking.
