Dracula by Bram Stoker

Another favorite for reading around Halloween. Who here is familiar with the actual book instead of the 5 million movies they've made on it?

I like Dracula, but the one thing I've always wondered is in all the movies (I know they change a lot, Frankenstein was almost a 180 turn from the book) they say to kill the vampire you must impale their chest with a wooden stake...they never have in it, like in the book at the end when *spoilers* they kill Dracula, they not only impale his chest but they also cut off his head. Now why don't any of the movie makers put that in the film?
