Reception The film received mixed reviews from critics.
13B Times of India gave the movie a 3.5/5 rating and said, "Watch out for some zippy cinematography, a stylized monochrome tint, and some snazzy editing. Great timepass. Go for it."
Idlebrain.com gave it 2.5 out of 5 stars and stated, "The first half of the film is a little boring. The way the story unfolds in the second half is good. But the flashback episode and the climax is not shot in a gripping manner. The plus points of the film are the story, cinematography, and Madhavan. The negative points are inconsistent screenplay and runtime. Though it has an interesting plot point, 13B fails due to lack of gripping narration."
Rajeev Masand rated the film 2 out of 5 stars and wrote, "13B is the kind of convenient thriller where you do get a twist ending, but the kind in which anything goes. The logic behind the twist and the back-story to the supernatural premise is so convoluted, it's hardly clever."
Hindustan Times gave the movie 2 out of 5 stars and stated, "If you like horror films, this one's par for the course, especially in the first half, where Vikram K Kumar uses the TV set for an interesting premise, the actors do their bit and the camera picks up suitably weird angles."
Rediff.com rated the film 2 out of 5 stars and said, "One simply wishes it didn't have to be such hard work getting to the point, for the filmmakers as well as the audience."
Taran Adarsh of
Bollywood Hungama gave the film 1.5 out of 5 stars and said that "On the whole, 13B is interesting in parts, not in entirety." Shubhra Gupta of
The Indian Express said, "Forget the irritating item numbers. Stay with the film, and you will come to a smart little end, and leave half-smiling, half-wondering: is this what the future holds?"
Film Journal International wrote in their review, "J-horror-styled supernatural thriller from India doesn't have the gore or intensity of the real thing, and for many in the mainstream, that's a relief. Low-budget-looking but effective, with a great central gimmick."
Yavarum Nalam Bhama Devi Rani of
The Times of India gave the film 3 out of 5 stars and wrote, "It is a neat entertainer without amateurish spook props. This is one goose bumps date you would want to keep".
