Mary-O James’s review published on Letterboxd:
This review may contain spoilers.
A well-made and incredibly effective piece of film making featuring a very strong performance by Essie Davis. It's in the vein of Shutter Island,the Machinist and Silent House wherein the protagonist is struggling with some very hefty post-traumatic stress disorder leading to their mental state becoming increasingly unhinged and more severely severed from reality. the Babadook is also a how-to in bad parenting.
You can also dance to this using Rick James' "Superfreak" -
"Well she's a very troubled girrrll (baba-dook! baba-dook!)"
