Every third Hindi film either borrows or is inspired from a Hollywood film. Sometimes, the rehashed version works. Most of the times, it doesn't!
Also, it's important to choose a story that would strike a chord with Indian moviegoers. Ru-Ba-Ru borrows from the Hollywood film IF ONLY [2004; Jennifer Love Hewitt and Paul Nicholls], a subject that would work on the DVD circuit in India more than at plexes. Reason: The storyline is too hypothetical.
Debutante director Arjun Bali's choice of the subject may be debatable, but you can't shut your eyes to the fact that he has handled the subject with dexterity. In fact, a theme like this would've blown into smithereens had the captain of the shop been an incompetent storyteller.
