The scariest scene in the film
I was more frightened by a scene in the middle of the film than by the ending. SPOILER SPOILER SPOILER
Remember that scene where the woman is drinking tea in what appears to be a greenroom. She hears some noise; looks around; goes back to drinking her tea. The noise continues. All of a sudden, evil Sadako's feet creep into the corner of the frame in that completely unnerving, jagged walk.
After I saw this film I was so terrified I had to sleep with the lights on for the first time since I was 12 (I'm 20 now).
"Deserve's got nothin' to do with it."
