What? It's just the friendly neighborhood serial killer.
- The scene where Maddie tells the Man she hasn't seen his face and will never be able to identify him and begs him to just go... and he responds by calmly taking off his mask, making it obvious that he doesn't intend to let his prey survive the night.
- And besides the tattoo on his neck, the Man's face is not some horribly disfigured or eerie looking individual...he looks completely ordinary and unremarkable, as if he was just a random person you would see in the streets.
- Really, Maddie's entire situation is this. Being deaf-mute, she's completely oblivious to her stalker's presence for a good portion of the beginning of the film, until he makes himself known when he sends Maddie pictures to her laptop...of Maddie herself reading from her laptop, with said picture having been taken just from a nearby window.
- The murder of Sarah, who desperately tries to get Maddie's attention as she is being killed just outside of her friend's house, and Maddie is completely oblivious due to being unable to hear her dying friend's screams. The thought of being unaware that your friend's murder in spite of being just a few feet away is enough to send a chill down your spine.
- Even worse for Sarah. The safety she needed was right there. But her deaf friend just cannot hear her.
- While trying to stay alive and alert in her home, Maddie notices someone banging onto one of her windows and goes to investigate. She sees the corpse of her friend Sarah being held up by the Man, being used to knock onto the window to torment Maddie as she is trapped in her own home.
- John Gallagher Jr's slimy, smug, and chilling performance as the killer.
- Maddie hides in the bathroom and awaits the killer's arrival as he smashes his way into her home. With her knife at the ready and struggling with blood loss, she's fully prepared to fight him to the death. Then, the bathtub silently has shards of glass fall into it, as the killer smashes the skylight and slowly enters the room from behind her. Maddie can't hear him and is initially oblivious to the danger as the man taunts her and prepares to stab her in the back. If he hadn't laughed against her neck, he would've killed her right there.
