I was seven when my older sister took me to see Hellbound Hellraiser II. I remember being so terrified by that movie that I had nightmares for months. I used to think that Pinhead was under my bed at night waiting to take me to hell. To this day, I can't watch that movie without being a little frightened, and I've never forgiven my sister for making me watch it the first time.
