There’s the suggestion that the corruption is systemic – the conspiracy goes right to the top – but the film is so busy skewering everything that it becomes unfocused, baggy.

This is a bold film that uses not a child vampire, as in Abigail, in cinemas now, but real children, and the adults charged with their care...

It's incredibly tense... it almost has a Hitchcockian edge.

The story was gripping, and the acting was solid. Despite the scenes that didn’t flow, I understand why they were included. I genuinely didn’t think I would be so gripped by a school-based film but here I am!
