Is this a sign?

Wild. I can't imagine how one would differentiate easily without quotations. That sounds so confusing.

Why? Is it a script and not a book?

You didn't like it because you were expecting a sexy vampire movie? Do some research before you go to a movie. Count Orlock has always been depicted as a horrifying monster. All this to say, if you want to see a great movie with fantastic subtext, go see Nosferatu.
