Films for TV have to be much closer to the book mainly because the objective with a TV movie that translates literature is to get the audience after seeing this version to pick up the book and read it themselves. My attitude is that TV can never really be any form of art because it serves audience expectations.
We all need to look into the dark side of our nature - that's where the energy is the passion. People are afraid of that because it holds pieces of us we're busy denying.
