I will copy paste, what I wrote in the WU thread.
Anurag, was, is and will remain the best and the most likable character of kasauti (season1 and season2) because of his nature of being the more compassionate one, flawed but the only character which shows character growth and maturity over time. And he is the only one who loathes himself for his mistakes, rest of the people are on a full spree of gloating about how great human beings they were/are.
I guess the purpose of this reboot was to reinforce that Anurag 1 and Anurag 2 is similar, they listen to their hearts, make mistakes, hurt Prerna, but still loves her in every possible way, be it as the friend, the boy friend, the father of their child, and last but not the least, he loves her the most when she does not even acknowledge his existence and hurts him the most.
This show did not run longer because, nobody wants to see Anurag sacrificing his whole life to keep prerna happy, he deserves a happy ending and finally after 20 years he will get one with his Prerna
.. I am just so happy, I do not care about anything else but the reunion of AnuPre 
AnuPre were meant to reunite, be in hell, heaven or in this planet, both the seasons ensure that .. so the idea that Pre was meant to be settled with her second forced love, was never a choice nor an option and not even a reality anymore, call her names and call him names, Anurag-Prerna were always with each other. Thank You Ekta, irrespective of the storyline and every complain we have, the essence of the theme of this show remains intact.
