The point of view depends on how we analyse things with in. Probably its RGV's point of view to show it as a betrayal. But as per my understanding, NTRgaru become old and need assistance in all terms especially emotional support which he lacks after Madam Basava Tarakam passed away. All children were busy with their lives. So he wanted a companion to share his entire life's glory. That is the exact point of time Ms. Lakshmi Parvati entered in his life. Being an educated and matured person she took the place. And on personal grounds no one can question thier togetherness as its very personal to their lives and no one affected by thier decision of remarriage. The point here is
By that time Lakshmiji took place in NTR's life, he is almost started depending on her opinion for everything. It would have been dangerous to the party as well as people in the state as Lakshmiji is not having appropriate political background. So it's very correct that Mr. Chandrababu Naidu garu to takeover the steering with his immense expertise of politics. As this was the correct decision at that time to save party, all the family members were with him. What kind of expectations they have then? So I don't think it was a bitrayal. Just it's my point of view that's it. Otherwise picture is good.
