Wot no poltergeists

Over the last couple of weeks we've been enjoying a new series on Sky Living, 'The Enfield Haunting'.  This is based on real life events and tells the story of a family in 1970s London who appear to have been subjected to a quite horrific haunting event by a poltergeist, which was investigated by various official bodies and never, quite, disproved.

The series includes some big names (Timothy Spall as Maurice Grosse, the main psychic investigator) and some lesser known but no less impressive talents (including Eleanor Worthington-Cox as the young girl at the centre of the haunting).  And it seems we're not the only ones enjoying it.  This review in The Guardian is also full of praise for the writing, the acting, and the atmosphere, which is nicely creepy with occasional moments of real shock, but without the nastiness or suffering so beloved of horror these days.

The article is more than just a review of the series, going into some depth about the psychological aspects of poltergeist activity and whether or not the Enfield case was genuine, or an elaborate hoax played out by an unhappy schoolgirl (with or without the knowledge of her family).  We'll probably never know, but the article's author makes one surprising and valid point: what has happened to poltergeist activity in the modern technological age?  I hadn't realised, but apparently this kind of psychic activity, which used to be linked on a regular basis to disturbed teenagers, simply no longer happens.

So, was it always a fake?  Are we all so cynical that we assign mundane explanations to anything the least bit weird?  Or have the poltergeists got bored with Age of Warfare and moved on somewhere else?
