The intro is straightforward and leads us without great detours into the title-giving cage. The set is well-designed and, above all, cleverly illuminated, so that the cage seems to stand in nothing, which emphasizes the feeling of lost and hopelessness very well.
In addition, Lucy-Jane Quinlan and Patrick Bergin have a strong acting duo. Quinlan is growing beyond her role because the screenplay has unfortunately not much more than to tell platitudes about his protagonist. It is overwhelmed with emotional ballast and can also correspond to any horror stereotype. In general, Dudley does not really know what to do with his captured booty and creates a lot of drama from the outside rather than throwing the victim back on himself.
