A low budget film that looks a lot older than it is, Dark Heritage is supposedly an adaptation of a Lovecraft story.
Some hammy acting aside this is a pretty good effort. Made in an age before CGI the effects and costumes are still reasonably effective for the presumably small amount of money used to achieve them. Good use of light and dark make for a chilling atmosphere throughout.
There are better films out there that deal with the same kind of story but this one is just about good enough to watch. Dark Heritage is one for the collection.
