Every horror movie needs a scare jump, or many for sure. But to abuse the scare jump and use it every single minute of the movie is overkill, and it's what gives scare jumps such a bad reputation.
In this movie they use the most monotone situations to use scare jumps along with an extremely annoying volume boost. So yes, at the 5 minute mark I started rolling my eyes, but the atmosphere sort of gave me something to keep watching.
Then again, lighting is all over the place, they open the door and its a pitch black apartment, next scene theres a lot of light coming in from the windows, it uses light to their convenience and not in a realistic way.
It is never clear why the characters are acting the way they are (brother, grandfather, girl in wheelchair (and her mother)), and even worse, the movie concludes with a "resolution" that doesn't really explains those situations.
I'm sad I wasted my "free On Demand movie" code for this. It is a waste of time, scare jumps and money.
