So today I rented Paranormal Activity because i didn't see it in the theater. So I watched the original ending where she throws Micah's body at the camera then sniffs him and does something with the camera. I heard there were 3 alternate endings. So I went to the main menu and clicked alternate ending only, but it just shows katie screaming and micah runs down the stairs and you hear him scream, then Katie comes in the room shuts the door, locks it, and walks toward the camera and just cuts her throat. what happened to the other endings??????
