Casting was marvelous in the movie , Shine played an luminous role . Aishu has done justice with the Kumari's character. The plot seems to be a bit short and not so welcoming a new imagination or idea. The VFX and cinematography was minimal. Somewhere i came across tumbad scenerio, well that was a level Kumari couldn't stand upto . Mollywood seems to outgrow the film boundaries is what we can understand from Kumari. My advice is one time watchable.
The twisted witchcrafts , legends in old Stories and installation of mantra tantra was long ago much portrayed in 80s movies such as sreekrishna paranthu starring Mohanlal and followed by Atharvam starring Mamooty. These are movie which we seems to watch again and again .
