Otherwise no record breaking hits in films trensetting/pathbreaking for their times of release.
It's sometimes funny and paradoxical! Others start trends but aren't consistent. He doesn't really start trends, or shatter records but is consistent and never goes in a "bad"/flop/semi hit phase!
Coming to topic, HAHK hasn't just inspired K Jo or Adi Chopra. It inspired likes of Ekta Kapoor and several Indian movie/TV show makers also to showcase Indian traditions in all their opulence and family dramas and get eyeballs. HAHK nearly permanently kicked out the poor man/villager from the media/pop culture narrative and made it all about rich kids and grandeur. All these serials like Yeh Rishta Kya Kehlata Hai with their focus on rasams, riwaaz and issues like whether to make dal-chawal or roti-sabzi and their happy resolution are from Barjatya universe only.
