By the way, I'm going to try and be as spoiler free as I can be. Though just in case, the rest of the post is after the jump. (Unless you're reading a direct linked page)
When they announced this move was a step away from haunted houses and based on this case... I wasn't super enthusiastic. The descriptions I had read been reading made it sound more like a courtroom drama and that just sounded pretty boring to me. Fortunately it instead focuses on Ed and Lorraine investigating the source of the possession and why it's targeted Arnie and his girlfriends family. This leads to a fun adventure with The Warrens chasing down spooky shit and getting into creepy situations. This leads into the return of the Cult of Ram from Annabelle and a different kind of villain for them to deal with.
Unlike parts 1&2, the movie isn't directed by James Wan. Instead by Michael Chaves, who was behind 'The Curse of La Llorona', which is generally thought of as the worst of The Conjuring franchise. Don't get me wrong, it's an enjoyable movie. Ed and Lorraine are as lovable as ever and you're really rooting for them to save the day. I still found myself liking the movie even though it's not as good as others in the series. It's not as bad as La Llorna either, but still has a lot of the same problems. I wasn't completely won over, but I had a good time.
