The Possession was originally titled "DIBBUK BOX" which in my mind is a better title. I hate it when companies assume that we need them to dummy down the story (or in this case the title).
At any rate it is one of those Trojan horse stories, in which the family brings home an unexpected spirit. While the story isn't very original, I was impressed with the special effects. Expect the movie to to land in the theaters August 31st.
