Miss Havisham is an important feminine literary figure in the tradition of Antigone (though it's significant that Antigone is fighting to bury something and Miss Havisham refuses, as it were, to bury the corpse). Like Hamlet, she's focused on what everyone would rather not know or would like to forget, and she seems crazy / stuck as well as bitter, but she's also a perfect prototype of a performance artist. She's intentionally hard to deal with inviting the audience to remain with the violated body, the evidence of violence.
