It really is a good movie Mr. Tarazkp. The song of the sirens is the perfect symbol of that which we desire. It shows us everything we can want as if it were at our fingertips, but right there, at that moment when we launched ourselves to have everything, we were left with nothing.

Odysseus, aware of this, faces the song of the sirens with great courage. He knows himself to be vulnerable, he is not a superhuman, and yet he chooses not to run away, but to face his own desire.
In this he reveals a path for true growth... not to run away, to face from the awareness of our vulnerability.

Mermaids are a symbol, of temptations (with many forms) is not reduced only to beauty, nor to the relationship between men and women. Every human being has desires and must consider how to face them.
