I was lucky enough to see this mini-series when it was first broadcast in 1997. It hooked me immediately. There is more than a nod to The Chrysalids and the Midwych Cuckoos (AKA Village Of The Damned) by John Wyndham, along with a dash or two of The Invaders (A Quinn Martin Production) "one man against the infiltrators" to spice things up.
The story is based around a coastal village in Norfolk which disappears in a huge explosion allegedly caused by vast amounts of surplus army explosives dumped underground in the village. All the inhabitants apparently survive (so we are led to believe) as they were led out to safety by two police constables - one of whom is played by Leslie Grantham of Eastenders' "Dirty Den" fame. And no-one would have ever been the wiser until some years later a photographer witnesses the death of a blue-chip company executive in a car crash and violent explosion - only to find the man alive, unharmed and unscarred shortly afterwards - and his suspicions slowly open up a huge alien plot to take control of the earth!
The scriptwriting and acting are superb and both play very well on the viewer's sense of unease and foreboding as so many seemingly unconnected incidents and strange bahaviour all begin to add up to something sinister going on behind a normal facade.
It's been a long time since I've seen such a good British sci-fi drama as this. The music is good too - quite haunting and yet catchy. I found myself humming the theme for a good while afterwards.
I'd have given this DVD five stars; but there are no extras on the DVD so it loses one purely for that. To me The Uninvited is on a par with The Edge Of Darkness.
If you enjoy sci-fi that could almost be real, then The Uninvited comes highly recommended... a British mini-answer to the X-Files!
