The trend I have seen in last few years say that any serial starts on a promising and different story. It ends up with similar type of sub plots and sub stories. Some garner high TRPs, while others fail forcing creatives to digress to original story. And when the serial stops fetching good numbers, it is brought to abrupt end. It leaves gaping holes many a times (Ladies Special, Bhaskar Bharati, Kumkum, Saat Phere).In fact if you observe closely many serials invariably have dead and arised from ashes formulae:KSBKBT, KGGK, Kumukum,Saat Phere,WRWMK to name a few).
For a change it will be really interesting if a serial is planned with a plot and exact number of episodes like it happened in 90s.A serial could go upto 90-91 episodes or even 25 episodes and pull the shutter down. It kept the story and interest intact. The viewers were FOOLED less. And focus of story does not oscillate between creative extremes.
Classic example will be that of Aap Ki Antara. It is one serial that should had been fixed.It was a great story with commendable performances.Viewers would have loved it, rather they ended up showing some salesmans stint, some adoptions, some goons.
Are any producers listening?
