I remember a novel I read years ago (left unnamed for courtesy's sake) in which a minor character spoke in an affected psuedo-hipster way. Her dialog was misspelled to show the drawls and slurring of her speech, and syllables in the middle of a word would be in ALL CAPS for emphasis. I could never figure out what she was supposed to sound like, but in my head it was "Valley Girl," and I skipped all her dialog.

I like a lot of the structural tricks folks here have mentioned. I like chapter-ending cliff hangers and story lines that don't intersect. I can even stand withheld information if it's handled in a fun way. One thing I don't much like is a story where the protagonist has essentially one goal, keeps getting close to it and then is frustrated at the final moment. Plottus Interruptus.

I was enjoying the hell out of Tokyo Suckerpunch until the hero had one too many plot complications drop into his lap. I almost quit the book at the end, which I pretty much never do.
