The first part of the film was genuinely terrifying, as was the ending. It freaked me out so much I think I might have nightmares. Seriously. At my age.
It was very unsettling and the music made me feel trapped and claustrophobic.
My criticism of the film would be that I had to get my viewing partner to explain parts to me, and I felt a similarity to the 2001: A Space Odyssey film whereby if you haven't read the book, a lot of what is going on remains a tiny bit too cryptic.
Still, very well shot, and entertaining. 7/10
