I've never seen TV shows like that, though having no television I don't know if any are broadcast in Britain!
Even so I enjoy "ghost stories" for what they are (pure fiction) and explanations of genuine mysteries. What I mean by a genuine mystery is the origins or purposes of some known physical event or thing, being unknown. E.g., just what was Stonehenge really for?
One explained of course it is no longer a mystery but becomes an interesting historical topic. Until that happens, I am interested in surmising sensibly, what might be the explanation - provided the account itself is credible.
For example I do not belive in "ghosts" but I do accept people can have uncanny experiences - so what has happened? The most common appear to be no more than simple sleep disturbances, so interesting scientifically. Or they come from instinctively heightened awareness, even fear, in unfamiliar places, especially after dark; so if you believe in "ghosts" the slightest cold draught, wisp of mist or odd noise makes you think "it's a ghost!". No it wasn't, but try calming someone's fear when they want it to be a "ghost".

For a larger-scale example, several years ago there was a programme (might have been a short series) on the radio about the so-called "Bermuda Triangle"; by a BBC journalist who had investigated the more infamous losses.
He did this really as a spare-time project; and he found by trawling through official reports, eye-witness statements etc. that all were explicable by various combinations of human error, misjudgement, neglect and negligence, some to a criminal level. All this occurring in a huge area subject to violent weather over very deep ocean.
He told us at the end he had written the manuscript of a book of his research. The publishers turned it down. Why? They told him most buyers were only interested in fantasy, not fact!
