There are so many ideas about vampires that are actually wrong. All this 'can't be seen in a mirror, turning into a bat, having visible fangs, etc.' that we all take for granted is actually WRONG, it all stems from Bram Stoker's novel Dracula. He was as guilty of changing the ideas behind vampires as any trashy (or non-trashy) vampire film/novel today. Vampires are very versatile in that they have no set appearance, we only believe this to be the case thanks to Stoker's novel. The only truth behind vampires is that they originally came from various legends and myths that originated in the Far East. The stories spread and were later thought to have come from Eastern Europe, in particular Balkan countries like Bulgaria and Romania (hence Transylvania as the setting for Dracula, as this is a real place in Romania). There were many different legends that all played a part in creating the modern vampire. Some legends did indeed hold to the sort of thing explored in Dracula (for example, having no reflection and turning into a bat). However, these same stories also allowed for facts that are used in fiction today such as Twilight (e.g. sparkling in the sunlight, rather than being burned, or drinking animal blood rather than that of humans - note this is also a case in real life, with the actual species of bat called the 'vampire bat'). Anyone who deosn't like Twilight is entitled to their opinion, although I have to disagree with the Twilight bashing that keeps going on on threads like this. I am a straight guy who enjoyed the film and the books, and I understand that I am in a very small minority here, but everyone is entitled to an opinion and shouldn't be harassed by ANYONE (before you all start on me) for said opinion. I was able to read the books and watch the film not knowing if I would enjoy them or not, but with an open mind, because I was aware that Dracula and our pre-concieved notions of vampires are not the be-all and end-all, but that they are based on centuries old legends that are just as diverse as vampires in modern fiction.
