... I don't understand. What's your complaint here? Is it somehow a bad thing for them to write a topical article that adds context to a current piece of media? I had no idea about these details of Bram Stoker's Dracula and it's interesting finding out more about it. I didn't realize The Last Voyage of the Demeter would be about dracula until seeing it and it's fun to read more about it.
So yeah, be less cynical. Some of us want to learn more about the world around us. Sometimes it's really tiring reading the comments here. Nothing but bitter old men yelling at clouds.
