While there are a few entertaining sequences in the final third of the movie, you have to trundle through quite a sloppy and uninteresting turn of events with some average to poor acting from its cast. You could take a chance on it if you're a fan of Linda Blair or have an interest in low budget Australian cinema, but ensure your expectations are low upon viewing.
Have you ever come across Fatal Bond?
