A mis verdugos castigué

I have to agree with those who consider Karloff an underrated actor. Given the nature of this film and its fantastic premise, he brings a real subtlety to the role. After each of his antagonists meet their untimely demise, there is just a hint of remorse and sadness. Who else in the horror genre would have underplayed it like that? Karloff becomes the walking conscience of his tormentors and apart from the films failings regarding plot, effects etc., I think it works quite nicely on the level of allegory.
