Clarification: This film is the answer to what would happen if you combined Underworld with Harry Potter and Mean Girls. By that I mean if you combine the actual scripts of those films you would make this movie. That makes it part action movie, part coming of age teen drama, part fantasy and completely unoriginal. Unfortunately for its box office numbers none of those genre's are what women look for in their vampire movies. Via the folklore of the film vampires a split into two groups. You have your Moroi which is what Lissa is which are basically your good posh sophisticated group. Then you have your Strigoi which are basically your run of the mill horror movie vampires.
Selling Point: Girly enough for teenage girls but enough eye candy to be guy friendly enough to somewhat be worth watching.
Female Vampire Factor: It's a vampire high school.
Rose has nothing vampiric about her despite traditionally a Dampir having at least some vampire like traits (see Bloodrayne). As for everyone else, you basically just go down your list of teen high school movie stereotypes.
Stereotype #1 - Lissa "The skinny blonde spoiled princess." (Lucy Fry)
Stereotype #2 - really sexy and kind of evil school headmistress. (Olga Kurylenko)
Stereotype #3 - Mia a female bully who has to talk about and put down others due to her own low self esteem. (Sami Gayle)
hot and slutty.
Stereotype #4 -(!!!!!!!!!!SPOILER ALERT!!!!!!!!!!) Natalie, the dorky virgin no one pays attention to who looses the glasses and mom hair and becomes a pretty sexy evil vampire. (Sarah Hyland)
