I am a bit surprised by the terrible reviews Call of Cthulhu has received. While it is not perhaps the best movie ever, or chilling and/or gory like modern horror movies are, that's not the point of the movie.
What it is, and it succeeds in, is a very faithful adaptation of the original story, following also its non-linear storytelling and describing events around the globe. The movie is also atmospheric pastiche of the 20s impressionistic silent movies. As such, it is very much worth seeing, of you are interested in how Lovecraft's stories would have been filmed when they first were written, and/or are interested in 20s impressionism in general.
