Poltergeist, a long time since I saw this and sure it's showing it's age but it is full of really bizarre Doctor Who style moments.
I can imagine a really horrifying reworking of the concepts in this film.
Poltergeist phenomena (usually destructive behavior by teen-aged girls who blame it on spooks to see if their stupid parents are actually paying attention to them) tends to happen in dis-functional families and centre on older children than 5yrs old.
Dominique Dunne's character would have been a better source for what was happening than a bit of shady real estate dealing and getting Carol Anne back seems a bit too convenient a happy ending.
Imagine instead a dis-functional Freeling family.
Steven spends so much of his time working on selling more homes to move up the property ladder that he has little time for his family.
Dianne sinks all of her time into domestic drudgery in between pot smoking binges and has hatched out two later in life children to make up for her lack of community ties.
Dana who can remember being the only child, resents her brother and sister and has become anorexic (shifting the decaying food gag onto her).
Robbie and Carol Anne pretty much live in a fantasy world of dolls and action figures and barely leave their room fearful of the forces of nature and isolated from their parents and having less and less in common with their sister who is entering reckless adulthood.
In a terrible storm Robbie is caught in a tree brought down through his window (confirming his distrust of nature and the outside world) and Carol Anne goes missing.
Dana claims to hear Carol Anne through the television set and soon everybody does but rather than go to the police they turn to quack parapsychologists who play along with the delusion.
They bring in a truly bizarre self-proclaimed medium into the mix and soon the line between hysteria and the supernatural become blurred.
Has Dianne been witnessing poltergeist phenomena or just smoking too much pot?
Has Carol Anne really been pulled into another dimension or is she dead in the swimming pool pit Steven's feuding next door neighbor has been digging? If so did she fall or was she buried?
Did Dana really hear the voice or was she just faking it for attention?
Is the Freeling house built on an unmoved graveyard or do the bodies bursting out of the ground come from somewhere else?
Why hasn't anyone gone to the police?
With so many remakes and re-imaginings going on it's possibly inevitable someone will do it with this film but the original told that version of the story reasonably perfectly so why not turn it into a really dark horror film?
Think more Guillermo Del Toro than the golden age of Steven Spielberg.
