“Bedeviled” (** out of four) was a weak horror thriller about five friends who are terrorized by an unseen murderous force after downloading a mysterious app to their phone which eventually takes over their phones, then their lives, and then their sanity. Potentially scary story about horror in the digital and social media age is too uneven and silly although it has a few good jolts every now and then. For a scarier and more twisted horror movie about social media, watch “Unfriended” instead.
