well, I read the Google reviews which mostly were negative.
Still, I did watch the movie and found it to be good.
At some places it was just mind blowing and Bhumi once again did a great job. In fact, she totally nailed it.
Arshad Warsi - superb acting.
Twists goes on till the end of movie
Title background music, at places where reqd give chills.
For Few shots, I wish I could have watched the movie at IMAX Or other big screen.
Yes, at some places it seems like dialogues are dubbed and few dialogues are also very poorly written.
Still, movie is worth watching and I find movie somewhere between 3.5-4 / 5.
I don't see any issues in remake of South indian cinema in Bollywood , it happens both ways. Giving -ve reviews just because it's a remake isn't wise, in my opinion.
PS : Durgamati's entry scene/shot is just fabulous.
