Query: Good concept, badly written

Like all James Patterson's books, this was a good story idea, but poorly executed. Patterson's characters are interesting and his plot lines are clever, but the dialog runs from awkward to silly, and his pacing is often confusing and forced. That's why his books do better as movies: a better writer gets to use Patterson's concepts with more realistic dialog and good pacing.
