They were horrible. When I read the book series, I instantly fell in love. I was so exited to watch the movies, as it would be my favourite series come to life. But when I saw the movies I was severely disappointed. The movies failed to remain any faithfulness to the books. The script as a whole was terrible, and the plot was changed so much it was almost unrecognizable in comparison to the books. I don’t ever plan on watching the second movie.
