Generation leaps never works on Colors TV shows

When story focus on their children

Balika Vadhu - When Story focus on from Anandi to Nandini. It failed to make impact on viewers and eventually ended few months later

Uttaran - People loved Ichcha, Veer & Tapasya's story but when they took leap & story focus on their daughter intially it was good when it was focus on Yuvraj-Mukta &  Aman-Meethi but after Ichcha's death & when  story was focus on  Meethi-Akash and Mukta-Vishnu show becomes worst & flop & lost its charm 

Sasural Simar Ka & Laado have also witnessed the same

Now Udaan is happening the same thing
