Thamizhan offers a conventional yet engaging storyline centered around themes of justice and societal reform. The screenplay is straightforward, focusing heavily on the protagonist's righteous battle against corruption, which resonates well with the audience. The pacing is uneven at times, with a relatively slow first half that establishes characters and relationships, followed by a more gripping and intense second half that escalates the conflict effectively.

The film's songs and music, composed by D. Imman, blend well with the narrative, featuring melodious tracks that complement the emotional tone of the movie. The background score supports the dramatic sequences adequately, though it does not particularly stand out as a highlight. Cinematography by N K Ekambaram captures the urban and courtroom settings with clarity, adding to the film's realistic feel.

Overall, Thamizhan succeeds as a socially conscious entertainer with strong performances and a message-driven plot, despite some pacing issues and a predictable storyline.
