Critical reception The film received highly positive reviews from critics, who praised its script, cinematography, and acting performances, in particular that of Fahadh and Soubin. The film appeared on many year-end and decade-end lists as one of the best
Malayalam films of 2019 and
the 2010s by several publications such as
The Hindu,
Mathrubhumi, and
HuffPost India. In a review for
The Indian Express, G. Pramod Kumar called it "a subtle, but lucid and vivid poem about abandonment and redemption of human lives [...] The importance of love within the family, the brutality of patriarchy that even an eccentric man can exert, and the healing power of human touch and compassion are vividly depicted by both the writer Syam Pushakaran and director Madhu C. Narayanan." Writing for
Cinema Express, Sajin Shrijith lauded the film as "one of those brilliantly written, once-in-a-blue-moon films that scores in every department ...
Kumbalangi Nights is not being liberal just for the sake of it—it doesn't shove its progressive ideas down our throats. It doesn't preach; it simply shows." S. R. Praveen of
The Hindu concurred, writing: "Madhu. C. Madhu has the cushion of Syam Pushkaran's perceptive and subtle writing for his directorial debut; even so he makes a mark of his own, helming the beautiful coming together of all the elements that make this film what it is."
The Week's Sarath Ramesh Kuniyl agreed, rating the movie 4 stars out of 5 and deeming it "a rare gem" and a "must watch". A negative review came from film critic
C. S. Venkiteswaran, who wrote: "In its compulsion to entertain and thrill without a pause, the narrative ends up incorporating in its stride all the clichés of the oldgen films – that of saving the damsel in distress, hero winning the heroine's heart and body, the climactic trouncing of the villain, and the happy reunion of the family in the end – all churning up a syrupy narrative that leaves the viewers at peace with themselves and the world." Joseph Antony echoed this sentiment in his review for
Outlook, opining that "the artistry of the film loses out to its political ambition [with] barely any of the invigorating spirit that makes stories interesting" and citing Fahadh's performance as one of the movie's few saving graces. The film has received polarising reviews for its depiction of mental health and counselling.
The New Indian Express praised the movie for its attempt to break the stigmatisation surrounding counselling, writing, "A counselling session has many misconceptions attached to it, holding many back from reaching out to a professional. As [Saji] walks out [of a therapy session] with a light heart, another truth is demystified for the Malayali audience - that of what therapy actually involves."
India Independent Films also commended the scene for being "played out subtly, and with immense respect to his state of mind ... [it] marks a watershed for depicting clinical mental health issues with the sensitivity they deserve." However,
CNBC TV18 criticised its choice of an apparently mentally unwell man as the antagonist, when his actions could have just as easily been done by a healthy person. Film critic
Saibal Chatterjee pointed out that mental illness "is a disease to be treated. Instead, Shammi becomes an embodiment of all that is wrong with masculinity ... [the film is not] sensitive to the sensibilities of those suffering mental illness." == Accolades ==
