We just cannot generalize & totally discard that all Indian serials are unreal& useless. We do have & have had some good & sesible serials. Most of KB's serials are different & nice with some social msg. The current Tamil serial 'Enge Brahmanan' is also good but how many will like this philosophical theme & watch is a big Q .We have had some good Hindi serials too like Hum Log, Buniyaad [Family dramas] , Fauji [ story of an army officer.SRK shot to fame thru this serial] ,Yeh Jo Hai Jindagi , Nukkad [comedies] to name few.
Cheating & Polygamy are not something new & nonexistant in real life. .. As Satish pointed out many of our Netas & cine stars lead polygamous life.Now a days its rampant even among the middle class.Not that i am trying to defend such serials & its producers...just pointing out some of the realities.Personally do not appreciate such topics.
Initial episodes of Kalyanam appeared interesting with a mystery plot. Now it too has started its downward trend.
