Robert Szabó’s review published on Letterboxd :
This is a real master-piece, although it's hard to tag it only as a horror/scary/thriller genre.
Having all the ingredients for one of the darkest grown-up fairy tales
Del Toro with only two movies managed to set the bar so high as you feel you want to include all the rest of the "ghost" chillers into a different category,let's just call them scary movies.
Clearly this is more than just a scary movie...this is pure fear,emotion and panic especially if you are a grown-up.
...is it only me or spanish language can sound a bit frighting at times?
