This what Dread Central is saying about The Marked Ones
"Let me be perfectly clear... The Marked Ones is in NO WAY a spin-off. This is 110% franchise canon, and if you're a fan of this series, this is the Paranormal Activity you've been dying to see. Questions are answered, the mythology is taken ten steps further, and when the witches show up, it's for a hell of a lot more than just to say "BOO." It's that damned good. We're talking balls to the wall fun and scares thrown at you relentlessly with an extreme amount of intensity! This flick delivers on all counts and is not to be missed. It's nothing short of a gift to fans. The in-theatre reaction to the movie was off the charts insane. My ears are still ringing!"
