Is not that love is strange but that people are strange. This is the underlying subject of this movie. I don’t know if it is only happening to me but, more and more, movie’s scripts seem to be attempting to recreate (but with a cast) exactly what one gets from a reality show: a window to peek inside the day to day activities of common people.
Boyhood and Two Days, One Night are examples. No twist, no drama, no decision making, nothing is going on with what is going on. Allowing the viewer to become a witness seems to be the only paragon to be attained.
John Lithgow, Alfred Molina, and Marissa Tomei delivered such great performances that the lacks in this script perhaps might go unnoticed to some viewers. To me, the loose ends were a bit obnoxious. I finished the movie with a dozen of unresolved whys associated to the story line.
Better approach had the underlying aspect of having to deal with the particularities of others. I for sure can relate to that, because, whether you are an orderly person or not, everybody wants to run their life as they wish and to keep their things as they deem necessary and the cosmos conspires against this will. Culture, habits, preferences, fashion, age differences, personalities… all of the above? To the eye of the beholder, these are the reasons why we (and not love) are strange!
