I'm going to second the late Richard Laymon. He's just the pits. Laymon's ideas were very limited, and when he got a good one, he killed it very quickly with cardboard characters, and pointless and directionless plot twists (ie. random events because he ran out of ideas). Plus there was the whole fixiation with rape, one of his rules seemed to be that his novels heroines had to somehow be sexually brutalized in every book, or there had to be a flock of chicks to get raped with her. I think Laymon was working out some...personal issues.
The only reason I sampled Laymon's work was because it was recommended to me by people I liked and respected who usually had good taste and others going on and on about how important to the horror field he was.
What boggled me most is the respect given to his "Beast House" series. I read the first book, The Cellar when I was younger, I suppose just after the 80's horror-lit boom had faded away and it stuck in my mind as one of the most idiotic novels, never mind horror novels, I'd ever read. Skip ahead to the early 00's...I raised the plot of the novel on a horror forum in a thread about "stupid horror books you've forgotten the title of", and several people got all upset with me for disparaging a "classic." The Cellar's actually on lists of the greatest horror novels of all time. And then I find out there were like four sequels. Ugh.
SPOILER for anybody who doesn't want to read these stupid books but wants to know why I find the "Beast House" novels ridiculous: you know what they're about? Ape-like creatures with big dicks that have mouths on the end, with which they make human women their sexual slaves. I shit you not--those are the monsters in these books, them and the odd sexually predatory human male so there can be some sex women -don't- like in the books. A lot of loving descriptions of these women's glorious response mixed with the usual Laymonesque rapes and atrocities. Really dreadful, pointless and ultimately idiotic.
