The stories were pretty good. Solid, content rich, well written stories. None of the them provided much of a twist, however.
In reading the introduction, and how (this fellow at least) was putting the writer of the Mythos into generations -- I felt that 'this' generation lost the stark undefinable terror that I, personally, feel should be present. The old ones are now things to be painted, or found wherever, to be discussed, there merits dissected.
Again, I understand this might just be me, but within a piece in the Mythos universe (if you will) just saying the name Azathoth should make loosen some screws in your brain. Say Nylarthotep and you seriously lose a couple years off your life.
"Eldridges" (or Eldritches, maybe, its spelled oddly) was probably my favorite if only because it was Mievillian in it's, albeit limited, scope. Very much like a Mashup of 'Kranken' and "the city and the City" tossed into the Mythos,
Anyways, I had my complaints, but I happily read through the stories and was left still thinking about them to some extent.
