It is defined as a horror.
Is it that, in real sense ? I do not know but, not doubts, it is a well crafted short film , eerie, poetic, cold, wise storytold scene by scene.
An old lamplighter, part of his job.
His poor house, a rat and, late, a stranger at door , proposing it the progress and new dimension of his job.
And, sure , a spirit.
But not the story itself seduce . It is familiar, old and well feeled by each generation. The acting and the cinematography. The tension and the bitter nostalgia. The loneliness of venerable man , the arrogance of the young one and the meetings with the spirit.
A film growing, in some measure, in yourself. A wise constructed interogation. And a profound inspired end. And, sure, the language as fundamental virtue.
