Die Saat des Teufels

The story is familiar with the fairytale, as both brother and sister are also named Hansel and Gretel. Instead of getting lost in woods and finding a gingerbread house, they're both fascinated by a car, and two men kidnap them and take them to a heavily secured building. Inside is a clinic full of scientists who work in illegal experiments. The poor kids are chosen as organ donors and they die in the process. Their ghosts return from the grave seeking revenge on all those involved. What happens are some gruesome scenes, as the kids behave like monsters. I found the tune being hummed by the kids throughout the film mostly annoying. I expected more to this film but the story became predictable.
