The title
I admit I only looked through the first 20 topics mentioned on the message board. But is it possible that the title also alludes to the obvious subject matters of loss, grief, and depression? Specifically, this movie is a sort-of character study about the deterioration of a mother's perception of reality following the father's death. A book appears. A book about the Babadook. And the story goes forward from there. My question is, could the title "The Babadook" be a hint at the "dadabook"? I'm probably reaching because I want to like this movie a little more than I did, but if the title is a simple rearrangement of the "daddy book", then it certainly lends credence to the overarching story of insomnia and loss from the death of the father, and most certainly explains the book itself. Sorry if this has already been expounded, I'm usually late to most parties.
