Lack of character development makes it difficult to invest in She Dies Tomorrow.
Although She Dies Tomorrow features instances of effective horror, it’s difficult to care about any supporting characters. Outside of Kate Lyn Sheil and Jane Adams’s roles, the rest of the cast simply doesn’t spend enough time on screen. What time they do have is used to banally banter about the mundane. At one point three characters argue about dolphin sex while Jane Adam listens, horrified of her own death. While it can be read as how carefree a person is before they grapple with their own morality, the execution is too shallow to develop feelings, positive or negative, for any one character. This applies to the entirety of the supporting cast.
