While the idea of having a monster living within you is somehow far-fetched,  the way it was presented was brilliant.  Sophia talks about it with a kind of acceptance that you will admire.  Somehow her condition echoes the reality of human nature. Aren't we all monsters in our own way? The monsters of greed, jealousy, prejudice and capriciousness devour people alive everyday.  While Sophia literally has a monster that appears on impulse, she was a lesser evil compared to the monstrosities of people who mask it with deceitful beauty.  Breath-taking musical score,  the extro song matched the film's theme.  Do check out this short guys.
