My two stars came from not knowing what was going to happen next and the pig masks. Ever since watching 'You're Next', I've had an instant creep thing going with animals masks.
One big strong star for the moment near the end where the intruder is hunched down in her closet. It comes from a knee-jerk reaction most of us have when someone sneezes.
I didn't particular like the flashbacks even though they gave you emotion for the characters. The scenes of her sitting in the back of the ambulance staring out into the woods were unsettling. As usual, I wanted the characters to do something instead of just sitting there at times.
My Rating System 1 ★ for any of the following:
A Good Story - that makes sense
Plot Twists - the more the better
Characters - acting, do I care about them
Emotion - did it evoke any, good/bad
Effects - SPFX, scenery, mood, setting
Repeat - would I watch again/recommend
Continuity - my OCD'ness
