The whole point about liking horror movies is, perhaps, the initial snobbery you, as an audience member, feels over the main characters.
“No, don’t watch that video that is said to kill everyone within seven days of watching it!”
“The house is haunted. Get outta there! Don’t stick around and film shit!”
“Don’t stay in that remote cabin. Go to a hotel.”
“If the Blair Witch or Bigfoot is in the woods. Don’t go into the woods. It’s that simple.”
But, in the end, you understand the curiosity, wonder, naivety and just plain human stupidity of these characters. Because they don’t deserve it.
Horror is a movie genre essentially about empathy. It’s why it is so intriguing.
