This movie has nothing to do with Lovecraft's story, at all. It's just a cheesy heap trying to ride on the success of the Saw films, using Lovecraft's name to give itself some semblance of credibility.
This one has it all- Lack of real plot, recurring scenes that have absolutely nothing to do with the story, horrible acting, and even worse music...
The ending was the most disappointing thing of all.
If this isn't on the Worst Films of All Time list, it very well should be.
If you ever see this in a video store, you'd do best to run as far away as possible.
