A screen adaptation of a book or series gives only minor indication of the quality of the book it is based on. So often it happens that bestselling books are adapted into TV shows or movies, and they end up being a huge disappointment. The Vampire Academy and Mortal Instruments movies are testaments to this. Other times, such as the case with The Vampire Diaries, they end up better, at least in my humble opinion. A book can be crappy and have a great movie or series made out of it, and a great book could have a terrible adaptation. Just like you shouldn’t judge a book by its cover, it shouldn’t be judged based on someone’s on-screen interpretation of it.
