It was kind of a lame overall attempt at continuing the franchise by branching off to explain the psychic woman. It had some good scares and definitely did a good enough job of covering the background of her character but I am just not really sure that there was a demand for this to be done. It seemed like a strange sideways move for the franchise as a whole.
I would still recommend the movie to people looking for a scare. There were plenty sprinkled throughout. Just could have been a standalone movie instead of forcing the connection to an already established horror franchise.
