A Doll's House is a must read for any student of literature. With this play, Ibsen provided the major spark for one of the most influential genres of drama: realism. This style has become so ubiquitous, especially in the world of film and television, that people just accept it as "normal." Just imagine how well a new franchise of Law and Order or CSI would be received if it was written in verse. Somehow we doubt it would have much mass appeal.
Ibsen's method of using the idioms of everyday speech has gone from an artistic revolution to being just the way things are done. Reading this play in class provides a great opportunity for students to analyze the entertainment that they are exposed to on a daily basis. A discussion of the beginnings of realism can help them to understand the construction of most everything they watch, and it can help them to see the roots and progression over time of this massively popular style.
