Already watched the conjuring part 1? Were you scared from the scenes? Did you find it horribly scary? It freaked you out? If the answer to all the questions is yes, then id suggest you to not watch this movie alone.
Well, the plot of the story is just amazing and the cinematography is astonishing. Although it is very scary and if you are a heart patient, stay away from the hall where conjuring 2 is being played!
Id recommend it if you have already seen the first part.
