Actually, I think it was a great movie representing the devout Catholic laity. The Warrens, the “paranormal investigators” are a couple with one daughter, and they are obviously devout Catholics. At one point, totally out of context of the horrors around them, the wife makes the comment to her husband about how beautiful the Perron family is – five kids and all.
The movie also portrays a big family as being generally happy and loving, unlike many elements of modern culture that suggest that large families are somehow abnormal and socially stigmatized. The movie places the Perron family in the context of economic hardship, with the father describing how they purchased the home at a bank auction, his having to drive his truck from New England to Florida, and his responding to the possibility of staying somewhere other than the haunted farm house by asking “who would take in a family of seven?” To me, the Perron family, though not themselves religious (i.e., the kids weren’t baptized), represented a happy family where both mother and father had accepted vocations to be heads of household, in what we would call traditional gender roles.
To counterpoint the Perron family’s traditional gender roles, the Warrens work as a couple, both husband and wife. They leave their daughter with her grandmother so they can both work the case. Mr. Warren tries to protect his wife from harrowing scenes, a protection which she rebuffs, demanding to work together with him. The movie certainly portrays Mrs. Warren as the person left to worry about their daughter while they are away. To me, their working relationship is a loving example of a couple with both parents working.
The institutional church is portrayed as bureaucratic, with a priest stating that the Vatican requires approval of this kind of case. In keeping with the dramatized action in the movie (taking 10 years of events and packing them into what seems like a month), the approval being slow to arrive is the basis for Mr. Warren’s decision to violate Vatican policy (canon law?). I won’t spoil the ending…
