I don't know if what has gotten me to stop reading several novels fits exactly into any of these categories.
Charles Stross' Neptune's Brood read for the first fifty pages like a the first person diary of someone who isn't very interesting. It was like reading a sequential list of events and choices the character made that, even in a fairly unusual situation, seemed utterly unmotivated. I don't know if it was an agency problem, a voice problem or if the seemingly fantastic situations actually just weren't. It felt like the boring parts of Connie Willis books where the heroine is spazing out, but it didn't feel like that was going to change.
20+ years ago someone said to me, "If you liked Banks' Use of Weapons, you'll love Brin's Startide Rising." So I bought the book, and wasted $7 and a week reading it. Again, I don't know if it is a failure of a combination of factors from the article or not, but the book just seemed trite. The characters talked like middle school kids, the "uplifting" thing seemed utterly unmotivated and juvenile - fantastic for fantastic's sake. It seemed like fiction for young readers, but it wasn't.
Both of these guys sell a lot of books, and I can't tell if I am unable to relate to their styles, or if this just is one of those things like the popularity of Jersey Shore and McDonalds.
These experiences, along with one too many Anne McCaffery novels in my youth, has made me really picky about who I will even attempt to read - especially if they have a ton of popular books - especially series. I don't think David Weber has much of a chance with me.
