I too doubt the show is going off air anytime soon, however much I would like that. Reasons being there are hardly any new shows in the pipeline for star and if Star has to start pulling off shows, there are much worse performers to face the axe now. Also show is now averaging 1.6 for the past 1 month with an increasing trend for now whereas it averaged 1.8 before that since after the Swiss track(even that had a very low trp of 2.1 to 2.3, in terms of ROI when you take into account the production cost of those 2 weeks) When you compare the trps then and now with the investment cost, I don't think the PH will be alarmed right now. They're going to ride this track out, for sure.
I'm only hoping that the completely lacklustute and filler episodes this week, culminating in today's car crash(literally and figuratively) of an episode is only becaus there wasn't a proper plan in place to accommodate parth's leave. From the little BTS we've got of upcoming episodes I hope the pace picks up next week. I only hope this week's horrible episodes doesn't reflect very badly on next week's trps.
As already mentioned by people here, this shows USP has been anupre, whether people want to accept it or not. Look at the number of comments on yesterday's SP post and just compare it with the comments on other posts of supposedly more popular shows. The fact that even online buzz is at an all time low now goes to show how disappointed all viewers are.
