A Ghost Story

How does this 2017 film explore grief, and how does it make use of the ghost, C’s, being almost unmoored in time to express grief? Why is the ghost tied tightly to the house and its location, even as he jumps around in time? Who or what is the neighboring house’s ghost waiting for? Why does the film use an aspect ratio that is reminiscent of home movies or early silent film? How does the film’s implicit metaphysics contrast with and contest the nihilistic or absurdist message of the ‘hipster’ man at the party, who argues that attempts at leaving legacies are ultimately pointless, due to the fate of planet Earth, and ultimately, the universe as a whole? What was the content of the note that C’s wife, M, leaves tucked away in the house as she moves out, that seems to allow C to move on? Does the fact that, before he died, he wrote a song expressing his concern that M will forget about him show that he, at some level, knew he would die in the near term? Does her note address this concern of his?
