Tom Heistuman writes: Let Me In does a pretty solid job of showing that being a vampire is very similar to being an ostracized 12-year-old. Neither of them have any real connections with people outside of their parental figures. Neither are allowed much freedom (Owen's mother demands that he stay in the courtyard and Abby can't go...anywhere), and both seem to have lost a vital part of childhood: carefree excitement. I find it a little too on-the-nose that Owen's wallpaper in his bedroom is a shot from the moon's surface, looking at the Earth. Isolation, it seems, is well known to these two adolescents.
