I think Naagin 5 was very well promoted and Colors is still promoting Naagin everyday.
I saw a lot of buzz regarding this season too. But the difference is I saw some people refusing to watch because of the cheel naagin thing and again some being excited about it. Naagin lost half of its audience in this.
Then the trp consistently decreased post Dheeraj & Hina's exit. If N5 even managed to hold the 2.4 mark that would have still worked. But 1.6 is too low for the initial days of Naagin 5. All the other seasons did so much better.
I like the casting but I think there is nothing to look forward to this season going by the storyline. The concept of cheel naagin was intriguing but then they couldn't bring out anything extraordinary out of it. And now they're getting married with black sindoor and chains...matlab kuch bhi. They're making this more OTT each day for trp which I feel is destroying the show further ( just how they did with n4 )
I hope Naagin picks up its pace after the wedding. Naagin's wedding always works.
They really need to maintain some consistency , concentrate on the development and not on the romance. The scenes lack the connection , even the romantic scenes have no charm because they don't seem to FIT.
