Whenever human beings start to question the true meaning of life, they are invariably led to explore more about arts and poetry. It is art as well as poetry which make human lives worth living. However, neither art nor poetry can sustain itself without a basic form of commerce. It is on these necessary lines that Argentinian director Eliseo Subiela has constructed his film "El Lado Oscuro Del Corazon". What makes his film interesting is that it makes good use of two leading characters a poet and a prostitute to illustrate his point. The emotional force of Subiela's film is quite strong as it talks about unusual uses of poetry. In one poignant scene, one sees how the poet sells his poem to a street vendor for food. The notion of freedom as well as individuality has been depicted from the perspective of the prostitute who never allows anybody to have an absolute control over her person. "El Lado Oscuro Del Corazon" is able to reveal itself as an important film as it informs us that although there is little commercial value for poetry, an honest poet would never compromise his dignity in order to sell poetry.
