The best Conjuring movie is widely regarded as the original "The Conjuring" (2013). It is praised for its perfect blend of storytelling, atmosphere, and scares, introducing the beloved paranormal investigators Ed and Lorraine Warren with a compelling, chilling story and memorable scares. It has become a classic in the horror genre and the foundation of the Conjuring Universe franchise.

Following the original, "The Conjuring 2" (2016) is often ranked as the second-best, noted for its creepy and emotionally engaging story set in Enfield, England, with iconic supernatural villains.

Other films in the series like "Annabelle Comes Home" and "The Conjuring: The Devil Made Me Do It" are popular but considered lower in ranking compared to the first two main films.
