Was thinking about Jump Scares today, because… well you know. And remembered one that really freaked me out back in the day. The calligraphy scene in The Eye from 2002.
Re-watching it for the first time in a few years, The Eye is actually pretty low on jump scares but it is extremely creepy. However, this scene is still effective as hell. Violinist Mun receives a corneal transplant, restoring her vision after 18 years of blindness. But her joy at regaining her sight soon turns to horror as she begins to see mysterious figures that foretell gruesome deaths. I think this particular jump scare works as it plays with your perceptions. Initially you are not sure whether this is just a trick of the eye. Hint, it’s not.
