Contemporary response Upon its theatrical release, ''The Blood on Satan's Claw
received mixed reviews from film critics. The Monthly Film Bulletin wrote: "The plot of Satan's Skin
, which concerns the spread of a Satanic cult amongst the children of a seventeenth-century rural village, is a potentially intriguing amalgamation of Witchfinder General and Children of the Damned''. The alliance of innocence and evil has always been a telling theme for horror, and here – for some of the time at least – director
Piers Haggard takes advantage of it.
Linda Hayden is excellent as Angel Blake, the leader of the devil children, and the sequence in which she attempts to seduce the local priest in his own church is extremely powerful. But as the film progresses, its script and direction lose in subtlety and gain in crudeness: the sequence showing, in nauseating detail, the removal of the "devil skin" from a girl is both stylistically inept and thematically irrelevant. And though
Patrick Wymark tries hard to put some life back into things for the climax, the atmosphere has by then been conclusively shattered." Peter McGarry of the
Coventry Evening Telegraph praised the film as "remarkable... directed at a carefully measured pace by Piers Haggard, [it] avoids all the clichés and concentrates on atmosphere. The photography is excellent, and there are fine performances."
Vincent Canby of
The New York Times praised the performances in the film, adding that it has "a good deal of the quality of an
H. P. Lovecraft work, in the vulnerability of even its heroic characters, as well as in its pastoral landscape that contains the threat of "eeveel" within every sun-dappled glade. Most particularly, it contains Lovecraft's perfectly straight-faced acceptance of a universe whose natural order may, at any time, be overturned by supernatural disorder." The
New York Daily Newss Ann Guarino awarded the film a two out of four star-rating, deeming it a "routine horror" film.
Modern assessment In the years since its original release, ''The Blood on Satan's Claw
has received critical praise. The film has also earned a cult following, largely owed to its frequent airing on network television which introduced it to a wider audience. In his 2010 BBC documentary series A History of Horror'', writer and actor
Mark Gatiss referred to the film as a prime example of the subgenre of "
folk horror", grouping it with 1968's
Witchfinder General and 1973's
The Wicker Man, each films that revolve around superstitions and folklore of Britain. This has led to the film, along with
Witchfinder General and
The Wicker Man, as being described as the "unholy trinity" of folk horror films in critical circles. Mark Dinning, reviewing the film for
Empire, wrote: "This haunting horror is as much
Hammer wannabe as a
Witchfinder General re-hash—and surprisingly effective on both counts... The whole thing, directed with panache by Piers Haggard (great grandnephew of King Solomon's Mines author, H. Rider Haggard), falls to pieces by the end, but the prevailing mood is hard to shake."
Time Out noted that the film "vacillates wildly between hilariously unconvincing and genuinely nasty" but praised the cinematography and musical score, awarding the film a three out of five star-rating. Writing for
Scream magazine, Fliss Burton noted that the plot is "convoluted", but no less described it as a "richly atmospheric film, with a pervading sense of dread". In an essay for
British Horror Cinema (2002), writer Leon Hunt described ''The Blood on Satan's Claw
as "an intoxicating, if not entirely coherent blend of rural horror, generational conflict, and fin de siècle'' bleakness", and draws parallels between it and
Margaret Murray's nonfiction book
The Witch-Cult in Western Europe (1921). In his book
Horror Films of the 1970s (2012),
John Kenneth Muir similarly praised the film as "a bizarre, frightening film despite the meandering of its plot, emerging as a creepy, atmospheric nose-dive into the irrational". Reviewing the film for its fiftieth anniversary, Michael Gursky of
MovieWeb commended it as "a gorgeous, weird little British chiller" that is "memorably moody and marvelously macabre.".
Themes and analysis Film journalist Brad Weismann cites the film as an example of several British folk horror films of the 1960s and 1970s in which ancient demons, gods, and other supernatural entities "crept into contemporary life". Writer Paul Newland notes in his book
British Rural Landscapes on Film (2016) that ''The Blood on Satan's Claw'' has also been interpreted as a "seventeenth-century-set articulation" on the "slow and painful death" of the
counterculture movement of the 1960s. Newland also comments the film's preoccupation with the English countryside and its "potentially subterranean" landscape, noting: ==Related works==
