Kangaroo presents a heartfelt family drama with a focus on emotional relationships and moral values. The story is straightforward and centers on the protective instincts of the protagonist towards his sisters, which forms the emotional core of the film. The screenplay is linear and predictable, relying heavily on melodrama and sentimental moments to engage the audience.

The pacing of the movie is uneven; the first half establishes the family dynamics and character motivations effectively but tends to drag with repetitive scenes. The second half picks up slightly with heightened conflicts and resolutions but lacks the narrative depth to maintain sustained interest. The film's songs and background score are minimal and do not significantly enhance the storytelling, with the music director's contribution being unremarkable and not prominently credited.

Overall, Kangaroo appeals primarily to viewers who appreciate family-centric narratives with emotional appeal, though it may not satisfy audiences looking for innovative storytelling or technical finesse. The direction by Raj Babu stays within conventional boundaries, delivering a film that is earnest but somewhat formulaic.

Prithviraj Sukumaran: Strong and earnest portrayal of the protective elder brother, carrying the emotional weight of the film.

Kavya Madhavan: Natural and convincing as the sister, adding emotional depth to the family dynamics.

Jayasurya: Supportive role with adequate screen presence, complementing the lead performances.
