The movie may not have followed the book, that's not the cast fault that's the directors choice. I love the cast from the movie and think they would make the show perfect. I hate when a movie and a show is made and it's a different cast! That makes zero sense to me. The books probably should have been a show to begin with if you ask me, there's too much detail to just capture in a 2 hour movie. I'm excited for the show, but at the same time disappointed because I know I'm going to be looking at the new cast like "that's not jace". So we will see, hopefully it's something I look forward to each week.
