When I first found this website about four years ago I remember trying to get information on THE SUPERNATURAL but there was none and it's only very recently someone has gone to the time and trouble of registering it . Hopefully someone can contribute more info at a later date .
As for myself I can remember bits of it . The title credits start with a blast of organ music with the camera panning across Gothic images of gargoyles . I remember it seemed very effective at the time when I was aged ten or eleven years old .
Each episode was self contained with someone being invited to an English Victorian club where they had to relate a true supernatural event in their life to be allowed membership and as with all these type of anthology stories they'd be a twist at the end . One of the stories was spread over two episodes and featured several gentlemen staying at a remote mansion in central Europe where a werewolf stalks them , another featured a doll that comes to life while another episode stars Gordon Jackson in a tale that reworks Frankenstien . It's interesting to note that this episode is unique in that the club members think this tale has no basis in fact , it's a made up story
The production values were typical of the BBC of the time , ie it was made rather cheaply with very obvious studio exteriors . I also recall letters to the Radio Times were very mixed with some viewers thinking THE SUPERNATURAL was a load of rubbish while some thought it was a fairly good drama . I personally liked watching it on a Saturday night but there again I was still only a child and it should also be pointed out that the BBC dropped the series after one season while the IMDb hasn't exactly been deludged with either info or reviews for this show which unfortunately may say something about its quality
Update Nov 2014 . After seeing the BBC 4 repeats it's as I suspected . Painfully slow , stagey acting and static directing and twists you can probably see a coming a mile away
