Has nothing to do with the real Ranch.
Only exploited the name.
Many things happened on the Ranch, and a good book has been written about it.

This is not a plug: I read the book: it does not tell all. Things were never said.
Suffice to say: there were no kidnapping or deaths on the Ranch...
Cattle mutilation, giant "un-killable" dog, UFOs sightings, poltergeist, strange
lights, felt presence, worm holes, etc...
There was never any viable footage, as wires were spliced for no apparent cause, cameras went dark: the phenomena did not want to be filmed.
Read the book: it could have been much better, IMHO, but still: a group of physicists from NIDS were part of it.
The film?
Well, reality was a better script than this one.
