The Conjuring 2 is the sequel to 2013 film The Conjuring and is based on the paranormal cases of real life paranormal investigators, Ed and Lorraine Warren.
The Conjuring 2 is an effective thriller. It opts for slow moving cameras in dark rooms, with strange spooky objects lingering in the background. It's a film that cares more about atmosphere than about graphic images, which makes the scares all the more effective. The strongest aspect of the film is the two leads. Vera Farmiga and Patrick Wilson play the Warrens, and they are both real characters that come to care about, not filler horror tropes that we anticipate biting the dust at some point in the film (in fact we hope very much that Lorraine's premonition of Ed's death doesn't come true!)
Over all, a great little spooky summer movie. Check it out if you're into scares and you want a little heart mixed into it.
