Insidious suggests that something harmful and terrifying exists in families. Something that comes from within rather than without. Of course it's one of a canon of horror films that explore the issue, but what is fascinating to me is that family is still a target for horror, and the object of so much anxiety. Here, it isn't the house that is haunted, rather it's the family members themselves. A new house can't save them, they are not safe anywhere they go, because the monsters are attached to them and not the house. However, the house is also subverted in Insidious. It no longer represents a safe haven, rather it's rendered completely useless, or if anything, naught but a playground for the damned. All of the seemingly ubiquitous things, like kids toys and closets become sinister, harnessed for the sake of creating fear and restlessness. Of course I don't need to elaborate on the obvious Hitchcockian allusions.
