his parents actually weren't that bad...
.....compared to the other parents in their social circle, joshua's parents weren't that bad. the movie opens with his dad telling another verbally abusive parent to quiet down. the mom has no interest in having a stranger watch after her newborn. the mom very pointedly made a judgemental quip at the school recital when the other parents were complaining. the dad goes to the kid's 'meet the teacher' when most of the other parents send nannies. the dad sits in the boy's bedroom in the dark reassuring him. the parents reassure him about his infancy by protecting him from the truth.
that's why this movie bothers me so much. the mother is suffering from the horrifying effects of post-partum depression, which complicates all of her relationships. it's almost as if joshua is exploiting his parent's situation and taking advantage of their vulnerability. which, of course, is a scheme far beyond his age capability.
which leaves the question: was he always evil, born that way? or, was he made that way? if it's #1, then this movie is one of the creepiest child-demon movies ever. if it's #2, then the movie is one of the most nihilistic parental-fears movies i've ever watched.
