Thaandavam offers a gripping premise with its unique protagonist who is visually impaired, adding depth to the typical spy thriller genre. The screenplay attempts to balance intense action sequences with emotional moments, though the pacing fluctuates, with a stronger first half that sets up the mystery effectively. The second half, while packed with action, tends to drag in places due to convoluted plot points and predictable twists.

The film's songs and music by G. V. Prakash Kumar are well-composed, blending melodious tracks with situational numbers that complement the narrative. The background score effectively heightens tension during critical scenes, enhancing the thriller aspect of the movie. Cinematography by Nirav Shah captures both the gritty and glamorous sides of the story, adding visual appeal.

Despite its ambitious narrative and technical strengths, the screenplay occasionally suffers from uneven pacing and underdeveloped characters, which may affect audience engagement. However, the film's attempt to portray a differently-abled protagonist in a mainstream action role is commendable and adds a fresh perspective to the genre.
