Weird fiction

In reading the Vandermeers The Weird anthology I noticed that it tends to be a single weird idea or element at the heart of most of the early examples of the Weird form, and think that what sets the New Weird in contrast for me could be that it tends to have a great many weird images and ideas side-by-side, in addition to the tendency for secondary worlds. An example of this taken to excess is Kraken by China Miéville, a novel I don't particularly like but from an author I particularly do. I thought I'd write this opinion down because I was reminded of it by reading this, by H.P. Lovecraft, about his own The Dream-Quest of Unknown Kadath:

""it isn't much good; but forms useful practice for later and more authentic attempts in the novel form." He expressed concern while writing it that "Randolph Carter's adventures may have reached the point of palling on the reader; or that the very plethora of weird imagery may have destroyed the power of any one image to produce the desired impression of strangeness.""
