This is my first IMDb review because for the first time, IMDb ratings have completely failed me. 6? More like a 2. I've watched teen horror flicks and slash flicks more entertaining and sensible than this.
The story is badly stitched together, there is emphasis on (nonsensical) action rather than words and when there ARE words the dialogue leaves you feeling awkward and frustrated. You wonder in what universe are humans supposed to behave like that? The dialogue isn't the only thing that's frustrating; add to that the camera angles, lighting, cinematography, transitions, and you're in for an annoying experience. If only a couple of these variables was done right, it would have made a world of difference.
There are plenty of decent horror films out there with the demon child plot so do yourself a favor and skip this one.
