The Times of India gave the film 3 stars out of 5 and wrote, "That a filmmaker can evoke at least a bit of awe while dealing with romance, amidst scores of sex-crazed rom-coms, is no mean feat. Between its simplistic approach to romance and lack of a strong conflict, there's a layer of magic in Malli Malli Idhi Rani Roju. That's more than enough to make you crave for more, especially for Nithya and Sharwanand's crackling chemistry". The Hindu wrote, "If you love old-world romances, Malli Malli… is up your alley. On the flipside, the film’s snail pace gets grating at times and the contrived ending...takes some sheen off the otherwise beautiful film".
123telugu.com gave 3.25 out of 5 and wrote, "Malli Malli Idi Rani Roju is a feel good love story which stays within your heart. However, the slow paced narration and lack of entertainment will not go well with certain sections of the audience". idlebrain.com gave 3 out of 5 and wrote, "Malli Malli Idi Rani Roju is a good attempt, but not engaging enough". iqlikmovies.com user ratings garnered 3 out 5.
