1. Protagonists with anger management issues (females in urban fantasy are often guilty of this). Flaws are good. Flaws that make the protag act like a hysterical female are not good. "I know I shouldn't go in that dark and dangerous place alone, but I'm just so emotional right now!" Ugh.Fortunately with those I don't get past the blurb, most of the time. So many seem so ... samey.
2. Fantasy that isn't fantasy. It's some rushed POS that I send back by page 100. Worse, it tricked me with a really solid opening chapter or two. (I liked the Wheel of "Over"Time and have read the entire series twice. Nynaeve & Matt ftw.)
3. Lack of depth. Dune series (initially), Wheel of Time (entire), Martin's GoT, The Talisman & Dark Tower books, The NeverEnding Story are all nuanced and contain multiple plots. And Pratchett, for the humor side of nuanced. Someone else on these forums made a steak vs. jerky analogy. I feel like too many recent books are of the jerky variety. If I want jerky, then I'll watch TV. Books should be better.
I gotta say, I'm frustrated with the local library. I've sent back the last 8-12 fantasy books I've tried because they bored me. All I can think is who green-lit this garbage? Did they even read it?
I tried Wheel of Time but couldn't get into it. Worth another try, you think?
