Critical reception Season 1 Shaheen Irani of
OTTplay rated the series 3.5/5 stars and wrote "Indu is not your regular damsel-in-distress story. While it begins like that, the story unfolds beautifully. It is among those Bengali web series that take its own time to develop but leave a mark once the setup is clear. By the end of it all, Ishaa Saha becomes quite the attraction, right after Suhotra Mukhopadhyay's." She also applauded Chandraniv and Payal's performances, the mystery factor maintained around Laboni's character and the non sexual spark between Isha and Suhotra during their on screen moments. A critic from
Binged reviewed the series and opined "On the surface, Indu is a suspense drama, with a murder, several attempts to murder, an unhinged woman and a mystery woman thrown into the mix. But scratch beneath the surface, and the stench of misogyny and patriarchy pervades the plot in every scene." Ishaa's flawless portrayal as Indu, Suhotra's screen presence, the world building, cinematography and the background score were praised. But the slow pace and not so great suspense build up were criticized.
Season 2 Agnivo Niyogi of
The Telegraph reviewed the series and wrote "The show holds on to the suspense, packs in a few twists and ends with yet another cliffhanger.

He criticized the slow pace, dragging on of the suspense and a comparatively weak storyline than the first season. Shamayita Chakraborty of
OTTplay rated the series 3/5 stars and highlighted "It builds suspense, presents a stellar star cast, endlessly beats around the bushes, and finally doesn’t reach its resolution. Since the makers and writers hold back most of the explanations, the season becomes bland despite the garnishing of acting, et al." She applauded the effortless chemistry between Ishaa and Suhotra and mentioned that as the only reason to watch the series. She criticized the excessive stretching of the storyline which makes the lack of content evident. Archi Sengupta of
Leisure Byte rated the series 4/5 stars and opined "Indu 2 is another great addition to the genre that keeps the audience hooked to the storyline. Although you don’t get the answers to some of the biggest questions, you are given an inkling to make up your own minds until the next season (hopefully) answers them." She praised Ishaa's performance but bemoaned the mystery for getting convoluted with every episode and criticized the makers for dragging the story and killing more people in the lieu of creating a new season.
Season 3 Agnivo Niyogi of
The Telegraph reviewed the series and stated "The new season is sluggish but delivers a resolution that feels earned. This season doesn’t leave things dangling. It ties back the loose threads from past seasons." He praised Ishaa Saha for keeping the show together, the more space provided to the supporting cast, Judhajit Sarkar as Indu's brother-in-law, Suhotro's wildcard acting his emotional chemistry with Ishaa. But he bemoaned the pacing of the series as "Some scenes drag far longer than they should, especially in the middle episodes where conversations keep circling the same points." Archi Sengupta of
Leisure Byte rated the series 3/5 stars and opined "Overall, a good season. Ishaa Saha carries this series on her shoulders, and she’s, as always, great. From her mannerisms to her charms, the actor does a good job of holding on to our interest." She praised the usage of all the characters that helped in tying all the seasons together, several callback moments to recall different things that will keep the viewers interested and the ending. Although she bemoaned the slow pacing of the final season and mentioned that certain unnecessary sequences slow down the series, mounting the audience's annoyance. == Remake ==
