The Valdemar Legacy (2010) is Lovecraftian horror movie. It was pretty good. It had some tension and it maintained my interest.
The main problem with the movie is the structure. It begins with one set of characters but then has a long flashback with a different set of characters and ends with the first set of characters ready for Valdemar Legacy II. Now, if I had part II queued up after finishing part I then that might be ok; but I didn't.
Spanish language with subtitles and if you watch it with the Amazon Video subtitles turned on then it provides subtitles for the sound effects.
The character Jervás was played by Paul Naschy who I would swear I've seen in more than one movie but I can't figure out which.
from imdb's trivia section :
The first movie in all Spanish's cinema history made without Spanish government subsidies.
That seems both impossible and yet somehow plausible.
