“Loop Track” (*1/2 out of four) was a desultory psychological thriller about a man (Thomas Sainsbury) on the verge of a psychotic breakdown who retreats to the wilderness where he is terrorized by a ravenous creature- or this simply a figment of his imagination? Give writer/director/star Sainsbury credit for trying to tackle psychological and social issues in the framework of a horror story but the result is wan and wandering. Spectacular New Zealand locations are one of film’s only assets.
