In the world of lifestyle and entertainment , Darr is frequently cited as a case study for character writing and background score. The way the film handles the theme of "obsessive love" has influenced countless movies and web series in the decades since. It is a staple in pop culture discussions, with the famous line "I love you, K-k-k-kiran" still being mimicked and referenced today. The film’s music, composed by Shiv-Hari, adds another layer of eerie beauty, perfectly complementing the thriller aesthetic.

The movie revolves around Siddharth (played by Shafi Inamdar), a successful psychiatrist who becomes the object of obsession for a young man named Kunal (played by Shah Rukh Khan). Kunal, a disturbed and introverted individual, becomes fixated on Siddharth's wife, Nisha (played by Juhi Chawla). As Kunal's obsession grows, he begins to stalk Nisha, leading to a cat-and-mouse game between Siddharth and Kunal.
