It’s not exactly about zombies, but the story follows a familiar zombie movie format. It leans more toward suspense and action than graphic violence, with plenty of unexpected turns. The performers deliver decent performances considering the material; the production design—sets, lighting—is generally well-handled, though there's some space for refinement in the directing, editing, and sound mixing. It’s difficult to discuss further without giving away key plot points. I will simply state that whoever was responsible for designing the central location should be confined within it; the design is appalling and demonstrates a shocking lack of competence.
