Vanitha Police presents a socially relevant theme with a focus on women empowerment in the police force, which was a relatively novel concept in Malayalam cinema of the 1980s. The story is straightforward, blending drama with occasional comedic relief, largely supported by the performances of the lead cast. The screenplay maintains a steady pace, with the first half establishing characters and conflicts effectively, while the second half delves deeper into the resolution of these conflicts.

The film's pacing is balanced, though some sequences tend to drag, affecting the overall engagement. The absence of a dedicated music director is notable, and the film lacks memorable songs, which is uncommon for Malayalam films of that era. However, the background score by Dhananjayan complements the narrative adequately, enhancing emotional and tense moments without overpowering the scenes.

Technically, the cinematography captures the essence of the setting well, though it does not particularly stand out. The film relies heavily on its cast's performances and the socially conscious script rather than technical finesse or musical appeal. Overall, Vanitha Police is a modest entertainer with a meaningful message but limited cinematic innovation.
