Some decent scares in 'Paranormal Activity 4'

Oren Peli’s low-budget 2009 horror ‘Paranormal Activity’ was a welcome injection of adrenaline to the horror genre.

Made for a reported US$15,000 (€11,441) and shot in the Israeli-born film-maker’s home, the first film grossed almost 200m (€152.5m) worldwide, giving birth to a franchise that has churned out sequels at a rate of one film per year.
