I was pretty disappointed with it - don't know why though, these 'paranormal Investigators' are all a bit flakey and desperate to believe any old bollocks.
I've read that the original story was that the abandonment was a young family living off grid at Luibeilt, they'd had a baby and the Doctor from Fort William had come out to do the health checks and told them the house simply wasn't suitable for a baby/young kids to live in - and that they either leave, or the kids would be taken into care (not sure I believe that either - early 70's Lochaber had plenty of families living out in the arse end of nowhere (
Sasaferrato ? - it's a house out between Kinlochleven and Loch Trieg) in not far off bothy conditions).
Bothies can be spooky places - add being tired, cold, flickering light from candles, noises from wind, mice, and deer and you've a recipe for scaring the shit out of yourself...
They didn't seem to be interested in any of that...
