I would like to tell you 2-3 things. These are simple, basic and most important things.
1. Do not drag the show. create problems and solve them in 1-2-3 weeks time. take no more time than that. start one track and finish it soon then start another. viewers love the show with all their heart which does not get dragged because the show becomes interesting, thrilling and fun.
2. Do not show too much negativity. having villains is required in any show but having them being successful repeated times in their evil deeds puts a really bad taste in viewers mouth. Do not let them thrive. people already have lot going on in their real life. when they turn on television they want to see good winning over bad. please keep the negativity to as minimum or moderate as possible.
3. Even though this serial has only started now, still i would like to say one thing. please don't give this show a sad ending. you can bring all sorts of trouble, torture, misunderstanding, separation to the lead pair and their family members but end the problems in 2-3 weeks time and bring the people back together. Audiences love watching comedy, fun, romance but Nobody would watch dark romance.
For a film it may work where the lead pair gets separated but for a daily show nobody would watch it. People's brain would explode if they follow the serial from start to finish only to find that in the end the lead pair didn't get back together, didn't get any happiness and didn't live happily ever after.
