I thought this was a cool movie. The way the "strangers" faded in and out of the darkness to only reappear again was very scary. I like the fact they didnt speak, only a few short lines by the female blonde.This film was simple with no special effects or outlandish death scenes. The only down fall I saw was I wish the end would have played entirely back to the beginning, im talking about the 911 call. Very scary movie!!
