The reviews here are quite polarized, perhaps due to misplaced expectations, if one expects to find logic or romance in this movie, they'll be disappointed, also the core idea of the movie is copied from the Hollywood movie "smile" still, I personally found this as a very successful attempt to indianise that idea, the connect & suspense are maintained throughout the length. The story is captivating & apart from the core idea, it still has enough elements to keep one hooked to the screen.
Though this movie has copied the concept of "smile" it's more entertaining than the original one itself. The credit here goes to the Indian adaptation of the script, sounds effects, special effects & cinematography, the acting too isn't bad.
If one is against the very idea of movies with superstitious themes then they might not like it, but if one is open to seeing it just as a form of entertainment, this is a great watch.
