Vellithira presents a heartfelt story with a focus on youthful romance and emotional depth. The screenplay maintains a steady pace, especially in the first half, where the characters and their backgrounds are well established, drawing the audience into their world. The second half, however, tends to slow down with some predictable sequences, which slightly affects the overall engagement.

The film's content is rooted in traditional romantic drama tropes but is elevated by sincere performances and a sensitive treatment of the subject matter. The songs, though limited in number, blend well with the narrative and complement the mood of the film. The background score is subtle and supports the emotional tone without overpowering the scenes.

Cinematography by S. Kumar captures the scenic locales beautifully, adding a visual charm to the storytelling. While the music director's contribution is not specified, the musical elements present are adequate and serve the film's atmosphere effectively. Overall, Vellithira is a decent romantic drama that appeals to fans of the genre but lacks a strong narrative punch in the latter half.

Prithviraj Sukumaran: Natural and engaging, effectively portraying the youthful protagonist.

Navya Nair: Graceful and emotive, bringing depth to her character.

Kalabhavan Mani: Adds a strong supporting presence with his characteristic intensity.

Jagathy Sreekumar: Provides comic relief with impeccable timing.
