If you like Edgar Allan Poe and "The Addams Family," you have a taste for mordant entertainment — that is, anything particularly grim or dark in nature.

The original meaning of mordant (which comes from the Latin word modere, meaning "to bite or sting,") was that of a physical substance that literally bit into something, such as the one used to set dye into fabrics, or etch lines into a copper plate. Now, mordant generally refers to a dark or biting artistic style, sense of humor, or psychological outlook.
