Eternal Sunshine of The Spotless Mind as an existentialist movie -
“The movie also acknowledges the harsh realities of modern relationships. The film concludes with the couple getting back together again, both of them knowing that it’s likely an exercise in futility; they will once again go through all the phases of the relationship just like before and ultimately tire of each other. But they choose to do it anyway — a revealing and truthful glimpse into the potential short-sightedness and undying hopefulness that’s a part of human nature and our ventures into relationships.”
