A superb explanation and review of a great movie like Arrival, this needs to be applauded as the Film is most unusual In its editing and how the story unfolds to the viewer , the explanation of the end of the movie by no film school actually makes the movie more enjoyable , which is unusual and its self . It's explained in a simple and concise manner About a subject and concept that is Alien and complicated to our normal understanding and acceptance of time , both the movie and explanation are of such a high degree . Time is malleable , linear or circular And intrinsically linked to language tangible thought process and freedom and constraints that we may unknowingly Embrace . This explanation goes goes further than just this movie it opens up other thoughts about language different cultures how we live our lives and time itself , it’s actually quite beautiful .
