Eyes Without a Face
From the title alone, you can probably tell that this movie is pretty grotesque. A world-famous surgeon goes a little off his rocker when he steals the face of a beautiful woman and tries to trade her image with that of his daughter's. His daughter is, unsurprisingly, missing a face. Spooky!
Goodnight Mommy
'Child from hell' is a classic trope, which makes this Aussie flick even more impressive that it pulls the genre off so well. Twin boys and their bandaged mother deal with who and what is real, and what is simply a misshapen perspective. This one has gotten lots of criticism and acclaim alike.
