Ah prequels...It's time once again for yet another installment in the Paranormal Activity franchise. I cannot believe they are doing a third. A prequel to the prequel. What's next? Katie and Kristi as zygotes playing with ghosts in their mother's womb? And from this trailer, it's Bloody freakin' Mary as "the source." Because yeah, we haven't seen this particular ghost in about 8 million other stories.
