Of course it's not really Dennis and Katie in 2005, however much the movie seems anxious to suggest that; but for that matter, why on earth do we need to have that framework narrative in the first place, except because there's no more elegant way of setting up the 1988 footage?And that, perhaps ought to have been the first sign that PA3 was conceptually broken.Because, being a videographer, his gut instinct is to put up cameras in his and Julie's bedroom, and in the girls' and eventually putting a camera on an oscillating fan between the kitchen in living room, steadily rocking back and forth.
The first two movies certainly had their moments of "wait, why the hell are you still filming?
" - PA3 consists of very little else, expecting us to believe that this professional wedding videographer makes a point of filming himself watching and cutting tapes, among its other contrivances; and the question of who, exactly, is meant to have found, reviewed, and edited this found footage is impossibly aggravating.
So, naturally, Daniel happens to pull out a tape marked "September 1988" from the box of tapes, and... At any rate, we cut to the 1988 tape, and we find that it was filmed by Dennis (Christopher Nicholas Smith), a wedding videographer dating Julie (Lauren Bittner), the mother of eight-year-old Katie (Chloe Csengery) and five-year-old Kristi (Jessica Tyler Brown).
As the movie progresses, Dennis grows absolutely certain that Something is in the house, Something that Kristi insists on calling "Toby"; Julie categorically denies this is possible and refuses to watch the queer happenings on any of Dennis's tapes.
In sum: characters who feel artificial are for the most part not haunted by a malevolent being that isn't scary even when it asserts itself, and the whole construction by which these people are put in front of us doesn't seem plausible in the first place.
