H.P. Lovecrafts Cthulhus Ruf

For this spooky season I try to read some horror books and Manga that I still have on my tbr pile at home. This year I start with this manga edition of the Call of Cthulhu. And while the images were beautiful, gorgeous and detailed (this manga has probably of the best illustrations of the manga I've read so far, which aren't that many mind you), I am honest and say that I don't think I really understood the story.
It felt a bit like an introduction or a prologue to a bigger story and then again maybe it is.
I think it would have been better for me if i had read the novel first to really grasp the meaning of this story. As for now I just think I'm missing something but as this is my first entry into the world of H.P. Lovecraft maybe that's just his style. I'll definitely get to the original Call of Cthulhu version and see if I just didn't like the story overall or if it's a Limitation of the manga genre.
3/5 till now (could change when I've read the original story or more of the Cthulhu myths in general)
5/5 for the illustrations
