Sketch offers a gritty portrayal of the Chennai underworld with Vikram delivering an intense performance as the titular character. The story is straightforward but effective, focusing on the emotional and action-packed journey of the protagonist. The screenplay maintains a steady pace in the first half, establishing characters and their motivations well, but the second half tends to slow down with predictable plot developments.

The film's pacing suffers slightly in the latter half, where the narrative becomes somewhat formulaic and loses the initial momentum. However, the action sequences are well-choreographed and add excitement to the film. The songs composed by S. Thaman are situational and blend well with the narrative, though none stand out as chartbusters. The background score complements the mood of the film effectively, enhancing the tension and emotional beats throughout.

Vikram: Powerful and intense portrayal of a loyal henchman with convincing action and emotional depth.

Tamannaah Bhatia: Adequate in her role, providing the necessary romantic angle but with limited scope.

Soori: Provides comic relief with timing that lightens the mood without disrupting the flow.
