The reboot of 'Kyunki Saas Bhi Kabhi Bahu Thi' has made a smashing comeback, scoring a TRP of 2.3 in its first week and beating 'Taarak Mehta Ka Ooltah Chashmah' and 'Anupamaa.' Smriti Irani calls the revival 'historic' as the show reunites its original cast after 25 years. The nostalgia-packed drama premiered on July 29 on Star Plus.
