Warning: the 12-rating belies some fairly adult content. I have fond memories of watching this as a 13-year-old with my parents and everyone getting hideously embarassed, so do watch out. This mid-80s BBC production is faithfully adapted from the Fay Weldon novel of the same title and is infinitely better than the hollywood movie version. Dowdy housewife Ruth finally flips out over her husband's (Dennis Waterman with a bad 'tache) latest affair and sets out on an epic mission to ruin him and his mistress, the romance novelist Mary Fisher. In the course of doing so she assumes various personas and affects a fair few other lives. As she takes on her She-devil mantle and approaches her goal things get progressively weirder and weirder, culminating in an admirably unsettling climax which the movie shied away from. The title and satanic-looking imagery on the box are misleading though - the show dallies with the paranormal but doesn't go much further than Ruth scaring a Romany lady.
There are a few technical problems, including the standard nasty washed-out look common to many eighties programs, some truly scary eighties hairstyles and makeup and some pretty leaden acting in places - Waterman's numerous temper tantrums are particularly laughable, though I think this is more the fault of the script. However when the most believable character in the production is Tom Baker playing a randy priest you know something is not quite right. These issues, however, wind up contributing to the general air of weirdness and really enhance the experience.
We've waited a long time for this to become available and I'm glad to say it's worth the wait.
