In the 1970s and 1980s, Hrishikesh Mukherjee and Basu Chatterjee made films that were realistic and, in industry terms 'neat-n-clean', but not arthouse. They catered to the popular tastes, relying more on substance than star appeal. Even if the films featured A-list stars, the actors were cast in roles that were devoid of star mannerisms.
In a way, Ahista Ahista also belongs to the Hrishi-da/Basu-da genre. The storyline is simple, the situations seem straight out of life and just when you thought that the film would charter the routine path, the twist in the story takes you by surprise.
