Upon release, Phobia received positive response from film critics in India. Sweta Kaushal of The Hindustan Times gave 4 out of 5 stars and concluded saying, "Despite the element of horror, director Pawan Kriplani manages to keep the supernatural, religious drama at bay and opts for a psychological mayhem that makes for an impressive viewing experience." The film was also very well appreciated by Taran Adarsh of Bollywood Hungama. Via Twitter, he tweeted, "Expect the unexpected... #Phobia is a spine-chilling, nerve-racking, well-crafted psychological thriller. Radhika Apte is simply outstanding."
Mohar Basu of The Times of India gave 3.5 out of 5 stars and said that, in Phobia there are minor glitches in the thrilling fare. He adds, that in the end, Phobia is an unnerving movie that plays skillfully on the fear of the unknown. Suhani Singh of India Today in her 3.5-star review, explained that Phobia doesn't just scare the audience but also outsmart them. In addition, she says that just when they think that they have solved the mystery, director and co-writer Pawan Kripalani knocks the audience from their seats.
A reviewer of Bollywood Hungama gave 3 stars out of 5, saying, "an intriguing screenplay that keeps you riveted through the course of the film and the ending surprises you to no end". Saibal Chatterjee of NDTV also gave 3 out of 5 stars and said that Phobia is a canny flick that places known genre conventions in fresh light, the kind that bestows new life on them. Shubhra Gupta of The Indian Express called the film a "genuine frightener", saying that the film pulls it off with pizazz, helped by a crackerjack plot and performances.
A review carried by the Financial Express mentioned,
Director Pawan Kripalani does an excellent job with the script and manages to deliver a fairly unique experience. The first half is taut and gripping but the script does sag into the second half and resolves with a climax that might be too abstract for mainstream taste. But paired with an excellent actress like Radhika Apte, together these two manage to win the hearts of the audiences.
Apte's performance in the film was singled out by many critics as noteworthy. A reviewer in Bollywood Hungama calling her performance "worthy of a National Film Award", stated: "Apte is so effortless and so much in control of the extremely difficult character that as a viewer you'd find it stunning." While Singh said, "The makers couldn't have asked for a better actress, as Apte was terrifyingly good in this psychological horror". Chatterjee deemed her "riveting" and said, "Phobia wouldn't be half the film it is without the mercurial Radhika Apte. Watching her on the screen as emotions flash across her visage is an unalloyed delight."
The background score and major technical aspects of the film including; the cinematography, the editing, the locations and the costumes, was also well appreciated by the critics. A critic from Box Office India praised the film's music and said, "Music by Daniel George is good and background score by Karan Gaur brilliantly captures the essence of the film, making the narration even more fascinating to watch." Also lauding the editing, which he called "Sharp", and technical aspects of the film he said, "Cinematography by Jayakrishna Gummadi earns brownie points as his camerawork brings substance to the story."
