Traditionaly Maha Episodes show major changes to current tracks or end of current track. This one (PR MAhaepisode on Aug 21) was just another regular episode with no major change.
For months Pavitra Rishta is #1 in TRPs and Uttaran (on colors) #2. Uttaran had major story change in their Maha Episode on Aug 21st. Just to counter that mahaEpisode, ZEE and PR team came up with this MahaEpisode.
I believe they should not use Maha Episode for such tactics rather maintain the importance of such episodes.
If they had a MahaEpisode on Ganesh Chatturthi when something major is expected to happen, it would have been worth it.
Same was the case when Zee came up with Maha Episode of Yahan Mein Ghar Ghar Kheli. The episode had no major twists in their latest mahaepisode.
I believe Zee needs to do better job of scheduling their Maha Episodes.
