Like may conversions from book to screen, the show runners rushed this. Harkness wove considerable complexly into the books that give them a very substantial flavor and set them apart from teenie bopper books like Twilight. This complexity is almost entirely dropped out of the series leaving the audience often bewildered why something is happening or why Diana is such a ditz, when in the books she has considerable maturity and deftness. Some of this could not be helped, but each of these books need at least twelve to sixteen episodes to cover the nuances. For example, while Diana and Mathew fall in love quickly, the book takes you through a variety of details that lends sense to the tempo of their relationship. In the miniseries, however, these details are dropped and the relationship occurs as sappy and co-dependent a la Twilight. In the books, Harkness goes out of her way to delineate a vampire's nature to dominate and Diana's tolerance for domination as a courtesy to species, but without giving up her self or her power. in the miniseries, Diana comes off as an emotionally frail and clingy dingbat when the book portrays here in quite another light. These are really, really important details that the book series very fine historical fiction and fantasy rather than just another girl-clings-to-vampire Freudian nightmare. While visually pleasing at times, the story line has been dumbed-down unreasonably. To truly enjoy these wonderful stories you will have to read the books or at least listen to them on Audible.
