The beginning is great but however the story is little non - exciting.
The characters perform very well
The cinematography is very very good
The thing that I'm not satisfied with is, where is the devil or ghost. In this part the face of the devil appears 2 or 3 times and that was not terrifying at all.
I think they should work on the visuals of the devil/ghost and more heart rendering moments are necessary.
I think this time the makeup while the child was "possesed" , is good but not terrifying at all and after that there is not much terrifying scenes.
For me CONJURING and CONJURING-2 is a good example of horror movie.
More examples are : Dead silence, The curse of La Llorona, The Possession, The exorcism of emily rose, insidious etc.
