All the lines were improvised. They did not know what the scares would be, and thus the reactions are authentic. This all adds up to a film that feels real, adding to the scare of it. The movie has a feel of a Japanese supernatural movie, with a bit of a slow burn leading to the finale. It’s also interesting to note the witch is never actually seen, adding the fear of the unknown. This was a groundbreaking film when it came out that, over time, has lost its appeal to a lot of people and is not quite as respected as it was when it was released. Still, one cannot deny this laid the groundwork for many, many "found footage" films that would follow in the years to come. This is not a perfect movie, but is still a very good one. I saw it in the theatre when it came out--I liked it then, and I like it now.
