I'm not big on horror, but I do love Mary Shelley's "Frankenstein." I just think it's an awesome book and I'm so glad they still read it in schools. I'm not all that fond of Dracula, either the lore or the place. In fact, I probably wouldn't enter Dracula's castle if given the opportunity. Vlad the Impaler left a lot of darkness behind and I think that place must remain insanely creepy. I saw it on "Ghost Adventures" and that's as close as I'd like to get. My great grandfather was Romanian -- hopefully I am not a descendant of Vlad. Though they love him in Transylvania. And not just because he's a huge tourist draw.
Back to Frankenstein. I love the way Mary Shelley came up with the idea while awaiting for an Italian volcano to blow. It's the ticking time bomb great fiction needs. She needed it to finish her story. The "real" Frankenstein's story is equally ghoulish, but he didn't have access to the numbers that Vlad did. I mean, Vlad's victims came to attack him. Frankenstein (Johann Dipple) had to go get his -- and at least they were dead.
Anyway, now the truth is mixed with folklore -- but they both have their place in history. Do you have a favorite?
