PR , in the past, has been such a good serial, with a fresh and fairly realistic storyline, a lovely talented lead pair with such good chemistry, a strong talented support cast who delivered consistently and a massive fan base.
The TRP decline of PR actually started around Aug 2011 (when KBC started) when it suddenly fell from a consistent 4+ to about 2 and was out of the Top 15 shows. The unconvincing leap followed by the contrived storyline of the secretary who went after manav and Savita-Sachu -saga really brought it down to 2. Then Sushant left in November followed by the 18-year leap and PR continued to struggle . After Feb 2012, PR has made it back to top 10 shows with a lower position (8 to 10) and a TRP 2.8- to 3+, which is nowhere near to what it was when the show was on Top 1-2 position for nearly 2 years.
The leaps and the unconvincing storylines, which only seem to be getting worse have taken PR to this position. People like me watch it only for Ankita as to me, she is such a delight to watch, even if it is only for one scene.
Im really glad that she has finally decided to leave. Her contribution to the show has been acknowledged repeatedly in the press and the awards she has got. As for the TRPs , well, time will tell.
For me PR ends when she is no longer part of the show.
