The film's success is largely attributed to the chemistry between its leads:

In Korean cinema, the mourning grave film reaches its emotional zenith with works like A Tale of Two Sisters (2003). While a psychological horror, the film’s most devastating scenes occur at the stepmother’s grave, where the ritual of cleaning the headstone becomes a battleground for forgiveness and resentment. The Jesa (ancestral rites) are cinematic gold for this genre—bowls of rice, incense sticks, and the deep bows to the earth become visual poetry.
