On a regular day, Rakul Preet Singh's Instagram posts could well double-up as tutorials for the average Joe to make the most of the ongoing period of isolation. But when she isn't using her furniture as workout props, busting diet myths, and indulging in play with her family members, Singh recedes to her couch to become more like us — indolent consumers of web shows.

"I have been binge-watching shows that have been recommended by friends. I saw one called Watchmen, which was [beautifully] written and unpredictable. It was Arjun [Kapoor] who had suggested it," says the actor, also adding that the Apple TV series, Loudest Voice, is another noteworthy addition here.

"It is not an over-the-top drama. It has been created interestingly and is based on the manner in which the #MeToo campaign kick-started. I also loved The Morning Show, and another gripping Netflix drama called Caliphate."
