I can't remember her exact words (sniff, memories are fading), but I believe Miss Snark had two sayings. One was 'Good writing trumps all'. The other was 'Plot trumps all'. Or something along those lines. Anyway, there was a contradiction between her much-vaunted belief that good writing was essential, and the draw of a darn good story - a contradiction that she herself freely admitted.
I've just run into this situation in a medical thriller. Not a genre I usually read, but it looked a bit more interesting than most. Here are a few of the issues I ran into within the first few chapters:
A monumental contradiction surrounding the murder weapon
Characters speaking like instruction manuals
Other characters perpetually in 'as you know Bob' mode
A tendency for the main character to forget the second half of a conversation she has just remembered, simply so she can remember it at a more suitable time later in the book
No Reason Not to Tell the Police what the main character has just unearthed
The mysterious ability of the main character and her boyfriend, supposedly madly in love, to have a shower together and not even think about having sex. In fact, as far as I can tell, they never have sex. Despite almost living together. With no good reason not to have sex. Without this being a plot point.
And more. In my eyes, the story was badly written and illogical. And yet...I read it to the end. Why? I think you know. Plot, people, plot. A good story, stuffed with twists and turns, gleamed through all the dross around it and positively forced me to read to the end. And (blush) I enjoyed it.
