Kinda by the numbers but it’s elevated by Farmiga and Wilson. They really bring a gravitas to the story and they are easily the most interesting part. I can see why these two characters spawned their own Conjuring Universe
Wan also has a lot of restraint throughout the film, opting for suspense rather than jump scares. A lesser director would end his film on that mirror and do a jump scare but Wan leaves the shot open-ended, ending in silence instead. Bravo
