This review may contain spoilers. I can handle the truth.
Pretty much a sequence of every horror trope you've seen in a home invasion/slasher movie,
Potential savior comes to the door unaware of the situation and comes this to close to saving the protagonist but dies? Yup
Protagonist has multiple opportunities to kill the attacker but just runs away instead? Yup
Protagonist being attacked by killer and a weapon is just an inch away from their fingers?! Yah.
