Um...wow... The Conjuring 2.
I don't actually remember The Conjuring all that well. It was a mashup of the Perron incident and Amityville, following notable paranormal investigator shysters Ed and Lorraine Warren. Conjuring 2, however, is all about the Enfield Haunting (an investigation from which, in real life, amusingly, Ed and Lorraine were banned after one day because they told the lead investigator how to monetize and fake stuff and, eventually, their comments would lead to the unraveling of their previous investigations as hoaxes).
Anyway... The Enfield Haunting is an awesome and creepy story. Instead of doing a mash up of jump scares, Conjuring 2 decides to loving recreate the location, people, and events of the haunting (with jump scares added in). They even do side by side pictures during the credits, which is cool, and play some of the original recordings.
Fun stuff, all around. And a great little Wiki hole if you want to read about the rise and fall of the Warrens (who in reality, only spent an hour in the Enfield house -- the interview scene from the movie).
