Plot: A Math Prodigy Finds a Match for His Mother
Agastya (Mihir Ahuja) is a 19-year-old math prodigy. He sees the world through graphs, numbers, and algorithms. His mother Vinita (Mona Singh), also called Vinni, is a single parent and real estate agent. Her husband left the family years ago.
Agastya meets Ira Raina (Angira Dhar), a sharp math professor at his college. Together, they launch “Project Mom.” The mission uses algorithms and compatibility scores to find a perfect partner for Vinita.
Vinita then meets Abhimanyu (Ranveer Brar). She feels an instant connection with him. This creates a conflict between Agastya’s calculated logic and real human emotion.

Critical Reception: What Reviewers Said
Moneycontrol (Rating: 3/5)
Moneycontrol’s review states that the series has a “clever premise and strong performances.” However, the review notes that the story “packs in too many things.”
The review praises Mona Singh for bringing “depth and ease to Vinita, moving smoothly between being a caring mother and a friend.” Mihir Ahuja delivers an “honest performance.”
The critic points out that when Agastya’s problem-solving approach becomes repetitive, “some conflicts feel forced and seem added just to push the story forward.” The ending feels “too predictable, and one can see it from a mile away.”
Times Now
Times Now’s review states that Mona Singh is “the strongest link of the series, connecting relatability with motherly warmth.” Mihir Ahuja is “honest, lovable and endearing as Agastya.”
However, the review adds that “in the quest to expand the mother-son’s simple tale, the episodes unnecessarily complicate the premise. The plot gets lost in the complicated math equations that should have been replaced by easy love formulas.”
The review concludes that a “predictable cliffhanger conclusion makes Maa Ka Sum lose its purpose and simplicity.”
The Tribune
The Tribune delivers a harsher critique. The review states that the “premise has potential, but gets buried under overwriting, convenient arcs and dialogue that rarely rises above the obvious.”
The critic takes issue with the Gen-Z dialogue. One character mocks Agastya’s reliance on mathematics with a crass metaphor. The review says: “The series sure has a way with words; the way, unfortunately, being a one-way potholed street with a dead-end sign.”
Another line from the review states: “It answers only one question: how do people with chronic back pain imagine Gen Z speaks?”
Aaj Tak (Hindi Review)
Aaj Tak’s Hindi review notes that Mona Singh and Mihir Ahuja share good screen chemistry. However, the review states: “Jo baat pehle episode mein samajh aa jaati hai, use sabit karne ke liye 8 episodes tak kheecha jaata hai” (What becomes clear in the first episode takes eight episodes to prove).
The review also points out a discomfort with Agastya’s character: “Maa ki zindagi ko ‘optimize’ karne ki uski koshish kahin na kahin pyaar se zyada control aur patriarchy ki jhalak deti hai” (His attempt to optimize his mother’s life reflects control and patriarchy more than love).
NewsCrab
NewsCrab states that the series has a “fresh concept” but “occasionally slips.” The review praises the mother-son dynamic but notes pacing issues in the middle episodes.
India Today
India Today notes that the show “does not sit neatly within a single genre” and instead focuses on “how a logical mind navigates emotional realities.”
Performance Analysis
Mona Singh as Vinita
Multiple reviews highlight Mona Singh’s performance as the series’ strongest element. Moneycontrol states she brings “depth and ease” to the role. Times Now calls her “the strongest link of the series.” Aaj Tak praises her comic timing and emotional range.
Mihir Ahuja as Agastya
Critics describe Ahuja’s performance as “honest” and “endearing.” Times Now notes that he uses his “youthful charm to create the right atmosphere.” Moneycontrol states he holds his own against Mona Singh.
Supporting Cast
Angira Dhar plays Ira Raina, Agastya’s math professor. Moneycontrol notes her role feels “underwritten.” Ranveer Brar plays Abhimanyu with limited screen time. Celesti Bairagey plays Annie, Agastya’s friend, and brings charm to a predictable arc.

Comparison with Other Mona Singh Series
Mona Singh previously starred in Prime Video’s Kaun Banegi Shikharwati (2022) and SonyLIV’s Jee Karda (2023). Critics note that Maa Ka Sum gives her a more substantial role than some of her recent projects.
Technical Aspects
The series uses mathematics and algorithms as recurring visual metaphors. Agastya sees graphs and equations overlaying real-world situations. Critics note this technique works in early episodes but becomes repetitive by the middle of the season.
Language and Dialogue
The series uses Hindi dialogue with English words and Gen-Z slang mixed in. The Tribune critic calls the dialogue “rarely rising above the obvious.” Aaj Tak notes that some Hindi translations of mathematical terms feel forced.
Target Audience
The series targets young adult viewers and families. The mother-son dynamic appeals to multi-generational audiences. The mathematical premise may appeal to viewers interested in unique, concept-driven storytelling.
Where to Watch
Maa Ka Sum streams exclusively on Prime Video. Viewers need an active Prime subscription. The service costs ₹1,499 per year or ₹299 per month in India.
Final Word from Critics
Moneycontrol gives 3/5 stars. Times Now recommends the series for performances but notes plot issues. The Tribune calls it a “miscalculated series of errors.” Aaj Tak describes it as an “over-calculated emotional drama.”
