This horror / thriller shows its limited budget and doesn't live up to similar films, such as Zodiac or Se7en. The excessive fake blood during the murder scenes remove any feelings of tension and make it almost comedic in places and the acting leaves a lot to be desired.
The plot also fails to deliver any real guesswork or tension and the viewer knows throughout what is coming next.
All that said, I think it makes for a good Sunday afternoon lazy film. No thinking is required and you can potter around, doing other things, whilst watching.
