Hey guys..since i m Colors channel follower...Let me tell u all some facts about 9:30 Slot...
Colors had many successful shows on 9:30..Like Laagi Tujhse Lagan which had even beaten YRKKH with 3.8+ TVR..TRP...In Year 2010
Then Came Mukti Bandhan which dint work well and was replaced by Parichay...this show was from Balaji Ekta so it did very well and even beat YRKKH in 2012...this show used to average 2.6-3.1 TRPs...
After that came Na Bole Tum Season 2 which was very popular due to season 1 ..It did wel initially but then averaged around 1.8-2.2 TRP...
Now i hope that Rang Rasiya atleast open up with 2.5+ Rating and average around 2.1 ..after that it all depends on story and concept
