Paul D’s review published on Letterboxd:
You can't kill your monsters, you just have to find some place where you can hide them away from the rest of the world.
The first half of the film just grinds you down in it's first half, in a relentless fashion that's reminiscent of The Texas Chain Saw Massacre. A single mother having to deal with a young son whose imagination gets the better of him and whose behaviour is becoming more and more antisocial, alienating her from what friends she has left, making it impossible to deal with other children and making the pair of them withdraw from society and into their own little world.
Monsters are real, there are plenty of them in this world, they just don't look like a cross between Nosferatu and Coffin Joe and hang out in your basement.
And for the record the creepiest thing in the movie is not The Babadook, it's that pair of social workers, the scariest thing about whom may be that they don't seem to do anything about an obviously deeply disturbed woman and a son who is clearly going to inherit her paranoid fantasies.
