First of all, it's not a horror - at best can be called a period social drama. It just uses the folk legend of the 'dayan/chudail' theme as a part of its story. The story is okayish - nothing that the audiences have not seen so far - havelis, debauchery of the landlord/ Thakurs, an idealistic 'England-return' barrister, greedy and conniving Bhabhis, and of course badi haveli ke bade raaz.
I read a couple of reviews comparing the movie with Rabindranath Tagore's works which I found laughable. Here's one of the reasons why - the makers have used expressions like Thakur moshai, but strangely, the devar always addresses his brothers wife as Bhabhi and not Boudi which is the correct expression. Nor does she call him Thakur Po which is the way it should be. Attention to detail is clearly missing. The story is lazily paced, there are many moments when you lose interest and wonder how much of the movie is actually left to be watched. The red light used liberally throughout the movie is annoying and hurts the eye - doesn't really look aesthetically appealing. There are no thrills whatsoever, let alone scary moments in the movie. Some scenes are quite disturbing and way too elaborately shot. I had very high expectations from the movie and perhaps that's why I found it pretty disappointing.
