The first big scare of the movie occurs while Rose is searching for her keys underwater. Out of nowhere, her search is interrupted when a decomposing corpse floats into view. Said corpse's eyes are bugging out and its mouth is hanging open. It makes for a rather effective Jump Scare.
Kazanian beating a cat and throwing it into a sack with several other cats he's likely abused in various ways. He then proceeds to take the sack outside and throw it in the river. As if that wasn't sick enough, he makes sure to push it with his crutch to ensure it goes under.
His death shortly thereafter, while well-deserved, is gruesome nonetheless. After slipping and falling down in the water, he is attacked by a swarm of hungry rats. It initially seems as though this is how we will end, but a chef in a nearby restaurant sees what is happening and comes sprinting out toward him. Just when it looks he's saved, the chef proceeds to chop at the back of his neck with a butcher knife. *Ouch.*
The creepy girl in Mark's class who gives him a rather intense stare while he reads Rose's letter and is unsurprisingly none other than Mater Lacrymarum herself.
Sarah coming across a strange man at work in his lab. Just when she is about to leave, he notices her book and removes his gloves, revealing a monstrous pair of hands that end in claw-like nails. He then forces her to give the book to him, while pushing her head closer and closer to a pot full of some boiling slop.
The scene in the apartment with Carlo and Sarah. The way the soundtrack cuts out every time the power does results in some rather off-putting silence. Additionally, Carlo emerging with a knife sticking out of his neck was... unpleasant.
Rose being attacked. Her death by an improvised guillotine is especially brutal, as it takes several tries for the blade to kill her, and even then it only gets about halfway through her neck.
