In its opening text crawl, The Conjuring claims to be based on a true story, though it probably doesn’t matter too much whether you believe that. Its main characters are Ed and Lorraine Warren, and they’re definitely real people: they’re paranormal investigators, best known for working on the case that would become known as The Amityville Horror. The events  of The Conjuring take place before that, though, back in 1971. The film weaves together the story of the Warrens with the story of the Perrons and their demons, creating higher stakes than normal for a haunted house movie. It’s not just the family of adorable moppety children that’s in danger: it’s the demonologists and their family, too. Though the Warrens are only quickly sketched, they’re clearly good people who care deeply about one another, which makes the danger lurking in the haunted house seem more menacing than it otherwise could have done. Even so, in other hands, this could’ve been just another generic exorcism movie. The script is competent, but it’s not particularly original. What makes The Conjuring special is its style. It uses its period setting to its advantage, borrowing the swooping steadicam shots and tight focus pulls of classic 70s horror; because it’s really 2013, though, it also nabs the best bits from more recent horror, notably Paranormal Activity. This is a film that revels in making you jump, and it’ll make you love it, too. The Perron house seems to have been designed deliberately to give its ghosts the best possible playground; it’s all long corridors, heavy doors, and endless secret hidey-holes. Even the wallpaper is creepy. The antique music box the Perron kids find in the garden could only scream “HAUNTED!” more loudly if it actually, y’know, screamed “HAUNTED!” when you turned the key, and its red and white stripes and spirals remind you exactly whose film you’re watching. The marketing can tell you this is a true story as much as it likes, but really, it’s James Wan’s show. From the ominously foggy lake beside the haunted house to the appearance of the inevitable creepy puppet, The Conjuring has Wan’s fingerprints all over it. And while his earlier movies were spirited, zeitgeisty, but ultimately flawed, The Conjuring is an accomplished work that shows that he’s matured into one hell of a filmmaker.
