Superstitious

Short, stilted sentences with little feeling. Characters often have reactions that make no sense and don't feel human, or even describe things in complete opposites, for example a character describing her boyfriend as caring and mellow whilst in the same breath mentioning how he goes off the rails if the slightest thing doesn't go his way (i.e. the opposite of mellow). This particular example could be seen as fostering an unreliable narrator, but I think that's giving it too much credit.
Occasional passages that work well and make me feel something, but they are very occasional. Basically this is a Goosebumps book except gorier and everyone is obsessed with sex.
