This is the latest film from the people who brought back the silent film to bring us "The Call of Cthulu". Unlike the earlier film this one is more modern in look and feel... but not by much. It recalls the style of the Universal horror classics and does a damn good job of it.
This is company that knows it has limited resources and makes the most of them. While some of the film is slow (there is a good 15 minutes that could easily had been cut out and no one would have noticed) the intention and spirit of Lovecraft is respected and certainly present. There is one scene in particular that is fairly gruesome and disturbing. Other scenes use animation maybe not possible with the 30's tech this film imitates faithfully in most places, but even those effects seem in place for this project.
Trying to explain a Lovecraft story is difficult at best and filming one, even harder. Changes must be made and visual choices to show what is indescribable can go either way with viewers but these guys get 100 points for effort and for actually getting it done when much more monied studios can't even get past the planning stages for putting Lovecraftian chills on the screen.
