To my mind, Lovecraft is not an author one typically reads because he's a good word-smith or even a particularly compelling storyteller, to me it's the sheer depth of imagination . I mean nobody ever wrote stuff like this before he did and he's inspired several generations of artists of all disciplines.
I can understand the sentiment toward Lovecraft's style -- it
is an acquired taste and not everyone is going to bother with it. But the whole notion of "he's not a good word-smith or compelling storyteller anyway, so let's just focus on his imagination and lasting influence" doesn't make any sense. Lovecraft is an author, therefore his craft -- both storytelling and word-smith ability -- is inseparable from the innovative ideas he had.
I'm not taking anything away from his stories as creative endeavors, either. nor am I taking away from his literary influence. Heck, I am not even criticizing Lovecraft in general (aside from his obvious racism, which doesn't particularly factor into
At The Mountains of Madness) -- My criticism is focused solely on this one story. The problem is,
even by his own standards of style,
At The Mountains of Madness is a very poorly written story. Yes, the revelations are fascinating, but it's buried under what even the Narrator of the story would call, "cumbrous details."
