All the characters that exist in the ever-expanding menagerie of mass media, whether they are a fully fleshed-out protagonist with hopes and dreams or just bare-bones stock side characters, have certain defining characteristics and personality traits that assign them to a specific character trope. Despite the complexities a character may possess when examining them underneath a metaphorical microscope, every single one falls into the trappings of a trope, some more obviously than others. The "Chosen One," the "Damsel in Distress" and the "Manic Pixie Dream Girl" are just some of the many blocks used to build characters. And when looking at the 2002 psychological horror movie May directed by Lucky McKee, it's abundantly clear that Angela Bettis' May embodies the "Creepy Loner Girl" trope.
