Thodarum presents a traditional melodramatic storyline that is typical of late 1990s Tamil cinema. The screenplay is straightforward, with a clear division between the emotional highs and lows, but it occasionally suffers from predictability and melodrama. The pacing in the first half is steady, setting up the characters and their conflicts effectively, while the second half attempts to resolve the tensions but feels somewhat rushed and formulaic.

The film's music and songs, though not credited to a specific music director in the available data, blend well with the narrative, providing emotional depth during key moments. The background score supports the dramatic scenes adequately but does not stand out as a memorable element. Cinematography by S. Murthy captures the emotional nuances and rural settings with competence, adding to the film's overall mood.

While the film relies heavily on performances and emotional appeal, it lacks innovative storytelling or technical brilliance. The direction by Ramesh Khanna is competent but does not elevate the film beyond its conventional framework. Overall, Thodarum is a moderate entertainer that appeals mainly to audiences who appreciate family dramas with emotional storytelling.
