Purappadu offers a compelling storyline that is deeply rooted in emotional drama and social commentary. The screenplay is structured to gradually build tension, with a strong focus on character development and narrative depth. The pacing in the first half is steady, allowing audiences to connect with the characters and their motivations, while the second half intensifies the drama, culminating in a powerful resolution.

The film's direction by Jeassy is marked by a sensitive portrayal of complex relationships, though some sequences could have benefited from tighter editing to maintain narrative momentum. The absence of a prominent music director and limited information on songs suggest that the film relied more on its story and performances than musical elements. The background score effectively complements the emotional tone, enhancing key moments without overpowering the scenes.
