Meh. One of the few books that I will ever say would probably be a decent movie, better than the book. Lion's Gate, get on that! ( )

Shelter attempts to mine a stressful environment for horror chills. Laura Craig is renovating a country house when her workers discover a strange underground complex swamped with fetid water. Being a horror story, it's only natural to assume evil things live in the water. The secondary fungal infection several people catch is honestly scarier than the actual monster. The build-up is very solid, but as action develops in the third act it can't live up to expectations. Awkward, bad sex scenes also spoil the mood. ( )
