"The Blood on Satan's Claw, a 1971 horror potboiler from English genre studio Tigon, lacks the moral underpinnings of Michael Reeves' cautionary classic Witchfinder General but resembles it in setting and atmosphere... The Blood on Satan's Claw clarifies the relationship between wickedness and virtue by showing how evil, in the guise of rebellious children and especially a seductive teenager, can be vanquished by vigilance and bravery on the part of Christian men... It's not just an enjoyable chiller with sex, violence, costume drama, and some amusing hairstyles, but also a dramatization — using the abolition of Catholic royalty from the English throne as a historical marker — of the tension between reason and superstition, between modern science and the long, regularly irresistible history of mythology." - Bryant Frazer, Deep Focus
