Kahani Ghar Ghar Ki: Can they sustain interest ?

This is another serial from the Balaji Telefilms stable, as can be somewhat guessed from the fact that the name of the serial starts with 'K', an alphabet that most of Ekta Kapoor's serials start with. It appears on Star Plus at 10 PM. This is another long running serial, with a number of twists and turns in the story, and the mandatory leap in the story of 2 decades happens (I believe more than once since the lead actor came into the story when she was a young bride, and now her daughter has a adult daughter). Of course, like with other time leaps, there is no change in types of cars, no change in the house, etc.
Sometimes, when you watch these serials for some time, it is very difficult to identify with these stories. These are rich people who talk of 500 crores without much problem, who worry about people coming after them and killing their husbands and sons, who remain the same (in fact, the lead actor Parvati (Sakshi Talwar) looks younger after a time gap of 18 years (some excellent plastic surgeons ?). And then you have people who are pure evil, such as Trishna (Mita Vashisht). The funniest part is when you read in the papers about some quarrel between an actor and Ekta Kapoor, and realize that either the person will have cosmetic surgery, or will suddenly die (Imagine changing the story of the serial to get rid of a character !)
So what is the story of this serial ? There is this Agarwal family (a big joint family) that live in a house that they love, and running a business. In the past, the episodes were mainly about the hatred by Pallavi (Achint Kaur) towards the family due to a failed marriage ceremony, and then a failed marriage. She keeps on trying to poison people towards Parvati, whom she detests.
Once these episodes were over, we have the spectacle of Om (the first son of the family and Parvati's husband) dying in a flood, and realizing that Om was also married to Trishna (the shock of knowing that the saintly Om was cheating on his first wife).
This is where the drama increased. Trishna was married off to Kamal (Ali Asgar) by Parvati, not realizing that here was another lady who wanted to take her revenge. She gets her revenge by getting Om and Krishna killed and eventually getting Parvati blamed by everybody (including elders and her own daughter who is suddenly shown in a negative light). In the meantime, Parvati marries Suyesh Mehra (Mohnish Behl) to get some money back, and then suspects him of killing Om.
After being successfully blamed by Trishna, Parvati goes to jail, supposedly dies and then re-emerges 18 years later as the rich and modern (and arrogant) Janaki Devi (with exactly the same face as Parvati). In these 18 years, Trishna has taken control over the entire house, and made everybody dependent and beholden to her. So now Janaki has to take her revenge on Trishna, her family members (who did not back her) as well as her daughter who believed her to be responsible for Om's death. In addition, Parvati / Janaki has to save her grand-children from the terror of Trishna. Right now, the story gets interesting from time to time, but the temptation to drag the serial is intense, and many times you wish for the serial to move on.
This is advertised as Ghar Ghar Ki Kahani, but I would not know a single household outside of movies where such things happen. This could be more appropriately titled as Kisi Aur Ghar ki Kahani.
