I looked at Brian Keen's free novel on his site ("Deluge") and checked out the start of his "Castaways", and maybe I'm just not in the mood, but I was very disappointed. Very. Every third choice of words seemed wrong, every third sentence off-balance; the structure of the narrative flow seemed horribly wrong as well.
It's not that I only like finicky prose; to the contrary - I can fully enjoy the simpler pulps of say Robert Bloch, heck, I can even enjoy a Stine, if only for the pace, which is otherwise impossible to find these days.
But my two attempts at Keene can only be likened to my attempts to read Sanderson's fantasy, only even more so. If trying to read Sanderson was not unlike watching an 80's Italian copy of Mad Max or Living Dead, then Keene was like watching an 80's Filipino copy of an Italian copy... Not in the sense of cliches or anything - I love cliches - I mean in the sense of every scene and every line in the movie being slightly wrong.
Opinion disclaimer: this is my personal opinion which has been known to change not only from year to year, but from morning to evening of same day. Or, in Internet speak: "IMAO BAO WAO, LMAO, HMAO, BUBAO". Oh wait, that's my takeaway order...
