When you go in a haunted house at, say, the fair, you make certain adjustments to you expectations for decorum. Going into an any normal house, you would consider it rude or silly for your hosts to keep a spring-loaded crone in the closet to launch at you and a bit sloppy not to sweep up the cobwebs. But in a haunted house, it's all part of the deal: you don't question the logic of it. That's a good thing for The Woman in Black because not a lot of it makes any sense. But it delivers some jumps (though diminishing jumps), and that's why you buy the ticket.
