What if Joshua isn't Evil?

This film was kind of weird in that it is so ambiguous. It shows the little kid being kind and loving to all the members of his family, and never shows him doing anything evil (he does disturbed things but nothing that shows intent to cause harm). The only horror is in the creepy score and surprise camera angles.

The back of my DVD says "is it all a series of eerie coincidences... or the calculated agenda of a sinister sibling with the perfect plan for revenge?" and this question is what i was left asking at the end.

On the basis of the evidence, I could argue strongly for the kid's case - he never felt loved his whole life, and after Lily was born he was abused by his mother first and then his father. And there is the title "Devil's Child" - are his parents the ones who are evil? They are certainly not model parents.

I would compare it to the book "The Turn of the Screw" in which a governess believes her two angelic charges are in the thrall of an evil spirit, and eventually kills them, though from her account of the events, there is no actual evidence.

This movie is not quite like that, in that the child ends up safe. I personally felt like it was a happy ending.
