Docs are possibly my favourite forms of media and I have seen many!
But hands down the one that stands out as one of the strangest was abducted in plain sight.
As a parent, these types of things are terrifying, but this kidnapper not only managed to kidnap the same kid twice (twice!), he also seduced the mum and turned the dad gay. absolutely insane levels of manipulation.
Of course, back in the 1970s, you could just cross state lines and make yourself a new ID using toilet paper and crayons, so I don't think this would fly now.
but damn, give it a look if you haven't seen it.
