I think the finger pointing @ the channel is just a CYA on part of the writers. After all, Jyoti had gone through some long torturous stretches, whether it was the Brij-Sushma abuse track, Sudha's Devika track, Jyoti's being kicked out track.
The channel can't be expected to bat for the show if its TRPs suck, and if Jyoti's TRPs went south, which it did since her marriage to Pankaj, that was due to the above tracks. Did NDTV Imagine at the time ask them to drag on Brij-Sushma, or take forever to make Sudha an item w/ Uday? And after Jyoti's divorce, and her accompanying self-flaggelation, the show was unbearable - Jyoti being abused by Pankaj, and yet going to mandirs to pray for him, and swearing by his pyaar ka nishani was sickening to watch - she was in some ways worse than Sushma.
Kabir's entry - the entry of a new funny guy into Jyoti's life - was what brightened up the show, and if that was interfarence by the channel to bring in this, kudos to them. Since then, though, they've morphed Kabir from a fun guy into a saint, starting w/ his rehabiliating Brij, and so on. I just hate his latest role - being a butt kisser of voters so that his father can do god knows what (he's the mayor - usually, people join politics so that they can be mayors, ministers, get government office. But here is a mayor more interested in party tickets. Why?)
Bottom line - the show has gone through ups & downs, and the CVs need to figure out how to keep the downs brief, or else wind up the show.
