I like it! I have only DMd 4 sessions so far, but it seems to do the "job" of d20 horror RPG very well. As soon as I have more time on hand, I will also write a detailed review for ENWorld.
The only thing that bugs me (I tend to be picky about that) is that there are quite a lot of minor editing errors and things left vague or unexplained (see Monte Cook's messageboard for an errata thread). So I would rate it 4 on a scale from 1-5 (5 being excellent) for that. A "revised" version incorporating all errata but changing nothing else would easily get a 5 in my book.
