The first Paranormal Activity annoyed me - and I blame the couple. The sequel annoyed me less but I still wasn't taken in by the new family - I only cared about what happened to their dog, an innocent who was undeserving of such annoying parents. The third film - I loved. The step back in time was a smart move and the kiddie actors stole the show. The ending whilst silly was effective and I came away excited for the next installment. And now it's here. And this Trailer is amazing.
