1. What does a book made in 1912 have to do with a movie made in 2012? Directors take creative liberties to improve source material they're working on all the time.
2. Why should I care about the reasons for why the movie was filled with cliches? If the book the movie was based on was a piece of shit, am I supposed to forgive a movie that is based upon that book for being a piece of shit? Of course not.
