I'll admit that I'm not a big fan of the Mythos as part of a reality outside of and larger than the "normal" D&D multiverse. I'd rather it be a part of it. Cthulhu and such can be demon lords and such, rather than being by necessity greater and more powerful than everything else. Maybe they represent a previous dynasty of demon lords or something, the way that the titans were overthrown by the Greek gods. Hounds of Tindalos don't have to be from "outside space and time" - they can be hunting creatures from the Astral Plane, which if I remember my Planescape right, was essentially "outside space and time". You don't have to invent new and grander places for these things to be from; I'd prefer to see them incorporated into as coherent a whole as possible rather than feel shoehorned in.
In this case, I could kind of deal with Cthulhu. If it was incorporated in, rather than automatically being a million times worse than anything you could possibly imagine ... then, okay. Maybe.
