Yeah the visuals of this movie are....not great. You never really see anyone's face, the video is grainy and there are very few moments where you can actually SEE anything. But for a horror movie, it helped not being able to see everything. It wasnt the scariest but there definitely parts where I was creeped out, I liked it. This is not a movie for people who like fast pace, not only is the movie slow going, there's not a lot of dialogue. The reason I like it so much is it creeped me out, which is what any good horror movie should do. Also it's open to interpretation so it's also interesting to get other people's opinion on "what was that"
Rotten tomatoes score is very accurate, most people won't like this movie based on the style
