Anantaram stands out for its intricate storytelling and layered screenplay, which demands active engagement from the viewer. The film's narrative structure is deliberately fragmented, reflecting the protagonist's troubled psyche and unreliable memories. The pacing in the first half is contemplative and slow, setting a reflective mood, while the second half intensifies the psychological tension and emotional depth.

The film does not rely on songs or conventional musical sequences; instead, the background score is minimalistic and haunting, complementing the introspective tone. The cinematography by Mankada Ravi Varma is exceptional, using visual metaphors and careful framing to enhance the film's themes of ambiguity and internal conflict. Overall, Anantaram is a masterclass in art-house cinema, combining profound thematic exploration with technical finesse.
