“Monkey Man” is a bloodthirsty, action-revenge story following the emotional crux of class struggles in modern-day India but painted parallel against the echo of a mythical Hindu legend. Being the long-awaited directorial debut of the British filmmaker, actor and writer Dev Patel, the film explores many angles of its protagonist’s emotional journey and the thematic developments that infuse it, but where it really shines is in its absolutely subversive action.
