The conjuring 2 is the sequel to the movie, the conjuring( it was the best horror movie I watched till date).
But now the place has taken by conjurung 2, let me give you an example, for a normal human being its very difficult to watch both conjuring on the same night.
You know what I mean, there are very less movies whose sequels are better and this is one of them I would strongly reccomend to watch conjuring 2 in theaters or the second option must be on vr glasses, for second option we have to wait for dvd to come out so go with it dont think twice, this movie is worth watching.
