This is totally a new concept of telling a scary story.
Rajkumar Rao and Pankaj Tripathi have given their best.
The dialogues and most importantly the delivery of dialogues is just awesome. Pankaj Tripathi steals the scene in every appearance. And Rajkumar Rao has now gone to altogether a different level of acting.
The movie conveys a message in a very humorous way. Do liaten the first song of movie very carefully, for a good comedy punch.
And also it gives you scary moments, when you jump off the seat. But humour complements the scary part so that even weak hearted can watch it.
Bollywood is now into totally a different way of story telling.
I am going 4/5 stars owing to the story, dialogues, and performances.
My suggestion is , go for this one.
