I think I've figured it out: teenagers don't feel like humans. Seems like every young adult fantasy romance movie features a scene where one person teaches some human-ish creature to be human. Here's a clip of that very scene from Beautiful Creatures:
Alice Englert and Alden Ehrenreich star in the film, which is adapted from the novel by Kami Garcia and Margaret Stohl. It follows a young witch named Lena, whose family emerges into the public eye just in time for her to fall in love before she is claimed for lightness or darkness.
Jeremy Irons, Viola Davis, Emmy Rossum, Emma Thompson, and Thomas Mann (Project X) also star.
Beautiful Creatures is directed by Richard LaGravenese, and will premiere February 14. Check out this Emmy Rossum Beautiful Creatures clip for another look.
