Finally got around watching it and i really liked it.
Very well made, suspenseful, with a great atmosphere, incredible performances (Essie Davis was brilliant) and a very interesting allegory. It's a psychological thriller and a character study with horror elements. The whole metaphor was by far the most interesting thing but at the same time it ended up as part of some of its weaknesses. And that is when the movie finally aknowledges that the Babadook is her guilts and her traumatic past. When we (as viewers) see it as a metaphor it's very interesting and exciting but when the movie and the characters see it that way also it kinda loses its power. That made the ending a bit anticlimatic to me.
Still a very original and worthy arthouse horror film. The writer/director is one to watch.
