Seenu Ramasamy heaped praise on the film calling it as a lighthouse to Tamil cinema. Ganesh Aaglave of
Firstpost after reviewing the film wrote "Courage and foolishness sail in the same boat. If an idea works, the ideator will be hailed as a trailblazer. And if it doesn’t work, the ideator will be called a fool. It’s as simple as that. And since Iravin Nizhal comes with many labels attached to it, I’d say it’s a courageous project. It’d have been a better movie, however, if the story had more depth than a two-litre water bottle." Srivatsan S of
The Hindu after reviewing the film wrote "Nevertheless, Parthiban does dare to dream big. He seems to enjoy taking risks, outdoing himself. Keep daring, Parthiban." Manoj Kumar R of
The Indian Express gave 3 out of 5 stars stating that "Parthiban has a reputation to keep. He is expected to do something different every time he makes a movie. And so he keeps inventing new ways to tell a story. But, it seems he isn’t changing the story much. He is just changing the way he tells it." M Suganth of
The Times of India gave 3.5 out of 5 stars and stated "There are several moments when you marvel at the smoothness with which the scenes transition from one time period to the next. Parthiban also uses music (AR Rahman, whose stirring score is like a ray of light in this film's dark world) sound effects cleverly to make us forget that entire film has been shot in one place, inside the huge set that we are shown in the making-of video. In that sense, this 'project' is definitely a success as Parthiban achieves what he set out to do."

The News Minute rated 2.5 out of 5 stars and wrote "Iravin Nizhal is at the least a crashing bore; at the worst, single-take magic aside, a noxious mix of misogyny and self-indulgence." Soundarya Athimuthu of
The Quint rated 3 out of 5 stars and called the film "A phenomenal addition to Parthiban's unique list of films". Gopinath Rajendran of
The New Indian Express rated the film 3.5 out of 5 stars and wrote " The film shows that with excellent workmanship and technological mastery, the boundaries of storytelling and filmmaking can be pushed to great limits—and sometimes, even if the story isn’t great, this is its own type of gratification." Vijaya Shankar of
DT Next rated the film 4.5 out of 5 stars and wrote that "Iravin Nizhal too comes with its flaws like its protagonist Nandhu but is an impressive experiment with technical mastery and unconventional storytelling from a filmmaker who always wants to give the audience something new and unique, which needs to be appreciated."
