I've always maintained that one should read a bad book to learn what not to do.
I just used fewer words.
Being a genre writer, my interest is providing entertainment. If something literary creeps into my works it is by accident, not design.
My heroes include Dorothy L. Sayers, who had the right answer for those who thought that a woman with her educational background should do something better with her talents than write mysteries. From Gaudy Night:
"I know what you're thinking - that anybody with proper sensitive feelings would rather scrub floors for a living. But I should scrub floors very badly, and I write detective stories rather well."
It is to be noted that many of the classics of today were considered trashy reading in the past, while many "literary" works of their contemporaries are all but forgotten. Conan Doyle, Chandler, Hammett, Ellery Queen, Mary Stewart, Tolkien, Bradbury, etc. were not good enough for the literati set.
Do a Google search for "bestseller" and any given year of the last century. How many of those books have you heard of, much less read?
Screw the literati set.
