First I must admit I have never been a Corman fan - all that spurting blood just never appealed to me. Yet something drew me to this, despite that concern, and I am not sorry I followed my hunch and rented this so many years ago. I tend to read the book either before or instead of watching movies, and Shelly wrote one amazing story. As much as I loved them, Karloff's movies had next to nothing besides the names to do with the book. As far as I am concerned, even though the story clearly does not precisely follow Shelly's tale, it is by far truest to the underlying depth of the book, and quite possibly the only film version that captures her primary theme of personal responsibility. The acting all around was good, especially considering some of the stretches required, and I quite enjoyed the special effects. Without going to wild extremes they were subtly effective and quite haunting. There were, of course, a few of Corman's trademark touches, but they fit the story so well even I could find no objection. As of this writing I have just watched this for the fifth time - quite a record considering I am still not really a Corman fan ;-)
