I am firmly convinced of this. I just saw the teaser trailer for Twilight [previously mentioned here and here], in which Bella, a mortal, falls in love with Edward, a douchebag vampire. Because the trailer usually provides a condensed view of the movie's tone, cinematography, plot and acting abilities, I have no faith in the upcoming film. It appears that it will consist of people standing around looking dyspeptic and occasionally making hammy, passionate proclamations, all with portentous special effects and no sense of humor whatsoever. Regrettable, really, when Kristen Stewart and Robert Pattinson are each young actors known for actually doing some good acting.
Wait...I take back what I said about there being no good vampire movies. Nosferatu is good.
