N1 started with a new concept of a naagin revenging for her parents murder..mistaking ML to be one of the killers...followed by falling in love and finding him innocent...later he was shown to possess some powers and they both ended the evil together..
N2 started with a repeat telecast of N1, where again naagin was shown revenging for her parents death and mistaking ML to be one of the killers...only to fall in love and to find he is not...the repeat telecast stopped only when he tried to revenge her back for killing his whole family and later turned out to be Naagraj himself, a positive one of course...then together they end the evils..and season ends with a baahubali twist- an open end...
Now N3 started same old with only difference that here Naagin was revenging for her lost love and not her parents...but change came when her love came back alive and her whole revenge drama turned futile...after that the show only revolved around Naagin saving the ML from evils...here they never even tried to experiment with ML by giving him something but continued to torture him with naagin saving him saga, until one day he finally dies...
Wonder how the mixture of 3 seasons will turn out to be? Hmmm....
