Lake Mungo (2008)
I decided to watch this movie because it had a lot of parallels with
The Babadook (2014). Both films have a sort of ambiguity about them as to whether or not the supernatural occurrences are real or brought about by grief, however I think
Lake Mungo does a better job at staying more consistent. I think a part of that is due to the mockumentary style of the film, where it feels like the truth throughout.
