It isn't all that great, actually. Really cheesy and very predicable of how certain scenes are gonna turn play out. However, I guess that's the charm of it all, because I would consider this one of my guilty pleasures.

It is interesting even when nothing much happens, which is for most of its 3-hour running time. Read full review

Mostly, the movie is committed to the value of a good time.

There is, somehow, an interesting story here, as well as some good acting. There are also some good scenes

A special offering in three reels that will excite enthusiasm. The story is from the tale of Edgar Allan Poe dealing with terror and horror and creating an atmosphere around the spectator that is likely to make him shiver. We were indeed astonished at the effectiveness with which the fearful tortures of the story's hero have been illustrated by the Solax producer. The sets are remarkably realistic and this is especially true of the dungeon-filled monastery, into which the luckless hero is dragged and in which, before he is released, he is tortured with fiendish ingenuity. The quiet occupants of many of the dungeons shown are skeletons and all the mechanism of torture, including the cell with the pit in its floor, down which we see skulls and crawling serpents (this bottom of the pit is not so realistic as it might have been) have been extremely well conceived. The pendulum, massive and sharp, which swings back and forth and ever draws nearer to the bound victim, is also effective, as is the manner of his salvation from it. Rats gnaw the ropes that bind him. Finally, we feel the walls around him growing hot and see them folding in on him. We have been watching the monks peering down at the man they are trying to destroy, their faces lighted by baleful fires, and we have noticed that the heroine has found help in a company of soldiers whom she is bringing to the rescue. Thus is created a telling element of dramatic suspense and it gives the picture "punch." The plot is strongly constructed. Darwin Karr has the central role and is at his best. The picture depends very much on his work and he rises to the occasion well, is imaginative and clear cut. He surely deserves credit. The others supported him fairly well; but there was little real evil strength in the monks; Fraunie Fronholz, the villain, is not at his best in such a role. The heroine (Blanche Cornwall) did good work. The photography is excellent. - The Moving Picture World, August 2, 1913
