The issue with “Sardar Ka Grandson” isn’t that it loses the plot over a completely ridiculous concept. The issue is that the film and its creators struggle to capitalize on the one true asset they possess. Neena Gupta plays the titular Sardar in Kaashvie Nair’s directorial debut. Unlike Gupta’s previous film “Badhaai Ho,” however, Nair’s film fails to fully exploit the actor’s abilities. Instead, the aspiring filmmaker focuses his attention and filming on the Grandson (Arjun Kapoor) in a dramedy that becomes less dramatic and much less comedic as the minutes pass. IMDB
Sardar makes her final wish at this point: she wants to see her home in pre-Partition Pakistan one last time. Grandson Amreek swears to grant Grandma’s wish, but there’s a snag. Apart from the fact that she is physically incapable of making the journey, Rupinder is barred from entering Pakistan for an odd purpose that you may or may not find amusing. It’s now up to Amreek to find out how to keep his promise. Up to that point, Nair and her co-writers (Anuja Chauhan and Amitosh Nagpal) do a good job of building up the plot, sprinkling passable humor with melodrama. The plot begins to deteriorate after Amreek devises a scheme to grant his grandmother’s wish, which is ironic given that this is the point at which the film should have become more enjoyable.
