“Dark Signal” (** out of four) was a visually moody but empty, pretentious horror thriller set in Wales about the spirit of a murdered girl who returns from the dead with a cryptic message and a stranded girl in the countryside (Joanna Ignaczewska) must team up with the staff of a local radio station to solve her death before it is too late. Director Edward Evers-Swindell displays a flair for atmosphere and shows some promise but his own absurd story sinks it all. Film has some scares in its opening but becomes slower and more unpleasant as it goes along and eventually breaks down.
