A simple but clever premise which draws upon horror traditions, especially the work of John Carpenter, is sustained throughout the movie to produce a memorable and tense 100 minutes.

The subject of sex, sexuality, disease, the transition into adulthood (you sense the director believes too early transition) and relationships between friends and family are played out against the backdrop of a once great Detroit. The films opening scenes summarise the movie perfectly and convey the central themes of the movie expertly.

Essentially a horror movie with a strong idea and ‘conservative’ message its strength lies in the realistic portrayal of teenagers, their relationships and what they think is the right thing to do faced with the horror that faces them and to an extent cannot escape.
