As for bringing Prachi back, I wish that it is not compared to Smriti's comeback. Smriti has for 7 years, essayed the role of Tulsi. Prachi's Bani cannot be compared to this iconic character. Prachi as Bani did bring life to this character, but of late, with her shooting alone, her acting is suffering. Plus, 6 months down the road, if Gurdeep does a good job, is it fair to her to be replaced? And what will Prachi's commitment to KS be 6 months down the road. Plus, Kyunki is a long running show and will probably continue for years, whereas KS, being a Zee show, may run till next year only. Zee shows never run for years like Star Plus shows.
I hope that at least here at IF, everyone gives the new Bani a chance. As for acting, Gurdeep had a difficult character to enact in Sindoor. She is in no way inferior to Prachi and deserves a chance. Here's hoping for better days for KS, esp hoping that the creatives do good work!!
