What a great portrayal of loneliness. Everyone in this movie is isolated from every other human being. The kindhearted and the bad alike. Trapped by their own inhibitions, anxieties and egoistic plans.
And the camera captures all of it and exposes human weakness with deadly precision.
And what a great allegory about our voyeuristic and self-exploiting society.
Don’t we do to ourselves what the evil filmmakers do to Marvin?
Of course, he is an extreme.
It’s so painful to witness how far he would go to make the loneliness disappear for a moment and how those efforts always try to find a new target. The sheer neediness behind his attempts is so overwhelming. He truly is a Sisyphus of Loneliness.
The camerawork really deserves special credit. The camera almost becomes another human actor.   Sometimes cold and observing in the back, then approaching and giving Marvin attention while listening to his dreams which gives him a feeling of belonging.
It is a demonically patient visitor who is not willing to leave even when the Instagram-potential of the images has long gone and was replaced by sad and naked reality.
