I remember reading quite a bit about htis back when it happened. A lot in the movie was fictionalized, especially the ending where they captured the entity in a frozen booth. That never happened.
However, from what I have read, it was one of the best documented cases of paranormal activity ever. The last thing I read was that the attacks continued with decreasing frequency until they finally stopped several years before she died.
Monsters from the id or spirits from beyond, there was documented evidence by accredited researchers of paranormal activity.
Thanks SD. Nice update.
Whatever works, use it.
A good idea stands on its own value independent of authorship.
If it stands or falls on the credibility of the author, maybe it isn't such a good idea.
