9Eli in Let The Right One In
You may better recognize this character as Abby in, Let Me In. Both are adaptations of John Lindqvist's Swedish novel but they do take on different approaches to the story. In the American film, Abby is a little more sympathetic - despite being a vampire, it seems she truly is
looking for human connection. In the original film, which is in some ways a closer adaptation of the book, Eli is far more manipulative. Although it's tempting to feel bad for her, there is always a sense that she is completely self-motivated. As she helps Oskar become a more confident and self-sufficient person, she also clearly has intentions of molding him into the type of person she needs by her side in order to stay alive.
