Storywise Naagin 1st is the best....It always had a reason for everyone to do something....Naagin 2 bhi ussi ka copy hai...but Romantic track ke alawa woh bhi teek Tak hai.Season 3 bhi Acha tha....But uss ke baad koi bhi season acha end nahi hai.....4 and 5 ka spinoff total timewaste dha...5 acha ban sakta dha...due to its fresh concept and the Actors chemistry..Dhamake ke saath start Kiya aur Diwali ki peeki phatake ki tarah end kiya..... Season 6 scriptwise 4 aur spinoff se bhi low-level dha...phir bhi actors ke wajah se itni din survive Kiya...But now it become a typical Balaji weekday drama show Leap seperation bacha and all.....
