Ekk Thee Sanam received generally negative reviews from critics. The film was one of the worst movie of 2013. Mihir Fadnavis of Firstpost stated, "With great vengeance, I have sifted through the cinematic trash can to collate the worst movies of the year. Because these movies weren’t hand grenades; they were atom bombs whose detonations of dreadfulness created Hiroshima and Nagasaki-sized mushroom clouds in my cerebrum and caused permanent damage to my mental harmony."
