Hell Yes. Extremely violent scenes and scary, paranoia inducing background.

* The doll. Good lord [[https://www.youtube.com/watch?v=qbPDLv33B7M the doll]]. The worst thing about it is that it has very little context. It just... shows up. The only context is that the killer has a fascination with creepy dolls and uses them as a calling card to scare the victims and in that case used it to distract the target.
* Amanda having her head repeatedly dunked into a tub of boiling water.
* Giordani's murder. The killer grabs him by the back of his head, and forces him teeth-first into the corner of a piano, before driving a knife into his neck.
* Carlo's death. Being dragged by a truck, slammed against a sidewalk, and having your head crushed by a wheel is not a pleasant way to go.
* Martha's [[OffWithHisHead horrific doom]], complete with GoryDiscretionShot.
