Critical response Edmund Lee of the
South China Morning Post classed the film "a minor gem" and rated it with 3.5 out of 5 stars. Appreciating it, Lee wrote, "there are so many moments of authentic humour and emotion throughout Pang’s meticulously scripted story that
Mama’s Affair must be recognised as a rare commercial product that nevertheless manages to stay true to its filmmaker’s artistic sensitivity." Phuong Le of
The Guardian rated the film with 2 stars out of 5 and wrote, "Teresa Mo’s measured performance, in spite of the cliche-ridden dialogue, is the real highlight of a film that is otherwise an empty star vehicle best enjoyed by fans." James Luxford, the
City A.M.'s film editor commented the film "While not a classic of Hong Kong cinema, Mama’s Affair does just enough to keep both sides of the age gap entertained, with warm family values moving in sync with pop hits". ==Awards and nominations==
