While N7 might have been planned initially as a 30 episode web series if the CV's wanted they could have gone to the drawing board and have a look at the earlier Naagin seasons specially N1 and N2.
The N1 and N2 along with N3 were roaring success along with N5 to some extent.
Specially the first 2 seasons of Naagin which presented the story of Shivanya and her daughter Shivangi-the script was strong storyline was simple characters were well crafted not over the top and proper use of VFX.
I had always seen shades of Shivangi and Shivanya in Ahana because she was presented as the Naagin with a proper killer Instinct.Her character has been let down due to her pairing with a Casanova.
The CV's could have presented Aryamaan having some personal traits of Maahir or Ritik even if he couldn't be their exact carbon copy.
The CV's had an opportunity with Yaman too-a proper capable antagonist with a ruthless mind only to be revealed as a mere con-artist.
Shesha and Vish were memorable villains not some mannequin like Radhika.
Yamini was never acting as some manequinn even when she was initially presented as a positive character.
Radhika being the Dragon wouldn't have been the problem if some proper indication or hints were given earlier.Her revelation has been totally sudden.
Where was the concern the care the unconditional support for Ahana from Arya's side?
The earlier ML characters showed their love not by mere words but by proper action too.
Yes they should have just followed season 1-2 format. Or even cheel naagin story with happy ending. As far I heard naagin an cheel died at end.
yes there is no proper story or any love wale feelings between Aryanta.
It looks fake from Aryaman side and as for Ahanna a girl like here would not give a second thought to someone who treated her like that . But it is in Indian show and it was suppose to be about Naagin and her Revenge but it got turned into saas bahu type wala show with Naagin taking down her enemies but sadly she was not shown strong enough.
And for once Ekta why do you always need a love story. Why cannot you show a naagin choose her duty over love.
One thing is clear .
They did not have story planned at all just ideas that kept changing.
Due to PR , Priyanka, Namik and Naagin fans they show is able to stay at top in trps and ott despite storyline.
itâs a fast paced show toh this bound to happen .
