Agreed, the serial makers need conflict to keep the suspense and interest going. At the same time, most (normal) viewers are not into S and M (sadism and masochism). Most of them also want to enjoy, have some pleasurable moments and evil should sometimes be punished even if it bounces back again.
In the case of Uttaran, day in and day out viewers have to see the person who they hate win and prosper. The makers have failed to achieve a balance between good and evil, conflict and enjoyment. If people watched so far, it is because they kept hoping things will change and evil will be punished in some small way at least. But now we realize that is not going to happen. Instead, we have to watch crappy tappy every day with her coy smiles and false tears. And Ichha with her pyar ka izhar for Tappu.
So mark my words, this serial is going to go downhill from now on unless they change direction. I don't know about others but I am sure of this. Simply because if someone like me who kept watching for so long has lost patience, then there are many others out there.
