The idea of the film inside a film is not new or uncommon, but here it is done very well by how tight it plays it. The action is essentially focused in one room with one actress and one computer; the character is editing a horror film although finds that the footage she is working on is footage of herself coming in her own door as she just did.
The delivery from there is deliberately twisted in the way it jumps from one scene to the next, but yet at the same time it is very simply done – it is not really as twisty as some suggest. Instead it is a solid thriller with the twisty element layered on top of something which already works pretty well. As such it is a solid piece of work that engages and creeps. The plotting is perhaps not as mind-f**ky as it would like to be, but it works in the moment, even if it doesn't have sufficient internal logic to work in the memory – although really, for a short film, it doesn't need to deliver this – and it works where it matters, during viewing.
