While some hate this franchise and the genre in general, I don’t. I’ve always been a fan of the “found footage” films.
Paranormal Activity and its sequel were impressive outings and I’ve felt they’ve been quite clever in their approach to the story. 2nd one was a prequel meshed with action from the original.
This one looks like an overall prequel to the story as a whole, going back to the sister’s childhood, something referenced in the 2nd one.
Directed by Catfish Henry Joost & Ariel Schulman, who know a bit about blurring the line between the real world, it should be an interesting entry into the horror franchise….
