When you can't finish reading books like 1Q84 because the storyline seems pointless and events seem too random to even care what happens to the characters. Also, not being able to get past the wrongness of the thirty year old man having sex with a seventeen year old regardless of the circumstances. The plot felt like a cover up, an excuse, as if the goal was to have sex with a minor regardless of the circumstances while blaming the circumstances for it happening. "It just happened," kind of b.s.
