Thiruttukkalyanam attempts to blend comedy with family drama, but the screenplay struggles to maintain a consistent tone throughout the film. The story is predictable and follows familiar tropes common in Tamil wedding comedies, which may feel repetitive to seasoned viewers.

The pacing is uneven; the first half is relatively engaging with light-hearted moments and situational comedy that holds the audience's attention. However, the second half drags with unnecessary subplots and a lack of narrative focus, weakening the overall impact.

Musically, Vaithi's compositions are average, with songs that neither stand out nor add significant value to the narrative. The background score is functional but fails to elevate the emotional or comedic beats effectively. Cinematography by Karthick Nallamuthu is competent but does not bring any distinct visual flair to the film.

A. Venkatesh: Delivers a decent performance with adequate comic timing but is limited by the weak script.

Tejasvy Jayakumar: Shows promise but is underutilized in a role that lacks depth.

Aadukalam Naren: Provides steady support with his experienced presence.

Nizhalgal Ravi: Performs competently in a typical character role.

Thambi Ramaiah: Adds some humor but is constrained by the screenplay.
