Ekta should watch UK soaps like Coronation Street which has been running successfully for over 40 years and East Enders for 20+ years. Both have continuity in the story line despite bringing in more characters.
Kkusum dragged on for years and yet left so many questions unanswered. Where was the moral of the story line. Innocent and honest person spends time in jail and yet evils walked away scot free with no punishment.
Too many characters brought in but side tracked without any explanations.
Did the ending remind you of another of Ekta's serial Koshish. (showing rebirth). Even that serial finished with some questions unanswered.
Message to Ekta that next time don't drag the story line and end it with some sense with all the characters involved without putting any more riddles etc. There should be continuity of the story with all characters and explanations.
