i actually liked it... with bhph there was always that realism, and im glad they didnt do the OMFG MIRACLE! she just HAPPENED to regain all that memory back! stuff...
and that little twist too, i mean it is sad for shravan but at the same time you can see how hes grown into a man, he can take care of his wife and himself, and hes selfless and loving enough that he willingly goes through this every day.
this story was about love and marriage, and in the end, this was a very fitting ending considering the circumstances, i believe, because again, it just shows how much love they have!
