H.P. Lovecraft's Cthulhu horror is both powerful and inaccessible because it is visceral. Cthulhu is a monster of indescribable horror that is being described. We are used to monsters in films, books and pictures so we can conjure up images of foul beasts easily enough, but it is decidedly harder to adjust our mental image when Lovecraft writes that "The Thing cannot be described".
Thus, the essence of Cthulhu horror is emotional rather than visual. Lovecraft tries to evoke the sense that the monster and the reality it belongs to is so morbidly incomprehensible that just bearing witness to it will bring insanity and inevitable death! This notion is not friendly to intellectual inquiry: we understand "monster" as something concrete but the Cthulhu monster is imbued with a fear of something abstract.

I enjoyed reading Call of Cthulhu because it was challenging to me; trying to comprehend what Lovecraft wanted to portray by writing a story about incomprehensible horror.
