Is e-martin the same person as E. E. Martin? Did she do a summary of A Doll's House?

There is a wealth of information on Ibsen's  here at . In addition to a summary of the plot of the play and a run-down of the characters, there are pages analyzing the themes, intentions, style, and historical context of the play. 

In reading this play for its most interesting elements, the symbolism and narrative parallels are very rewarding points of focus. 

The use of language begins on a symbolic level in Nora's first discussion with Helmer. He refers to her as a "singing lark" and we quickly see that she is hemmed in with specific and somewhat rigid gender-oriented expectations from her husband. She is, metaphorically, a bird in a cage. When she finally leaves in the end, she is achieving a freedom that this use of symbolism helps to paint as a natural and deeply felt impulse to spread her wings. 

There is also a variety of meanings surrounding the notion of debt in the play. Nora goes into debt to save Helmer's life when he is sick and in doing so becomes isolated in a lie. Helmer, unaware, is thus indebted to his wife for his very life though he presumes that she owes him a debt as the husband and protector-figure in the household. This situation underscores the play's social-political theme as it examines the gender-normative attitudes at work in the culture of the time.

Forgery too is a notion of complex usage in the play as it applies to Nora and Krogstad both but also as it is implicitly complicated by the question raised in the play about Nora's ability to have ideas of her own. (If she has no ideas of her own, how can she be held accountable for any actions she may take, whether they are technically criminal or not? When she forges her father's signature, the play subtly asks, is she acting independently and so destroying the patronage that yokes her, or is she instead somehow continuing to act as a dependent-minded wife and daughter, beholden to the will of the man of the house?) This is not to say that Nora's forgery is attributable to her father or to Helmer, but rather to point to the play's treatment of forgery as being far from simple because it resonates with ideas of weakness and strength; independence and dependence.  

Examining a social fabric that has seemingly begun to unravel due to internal pressures and unfortunately hypocritically absolutist and categorical judgments, A Doll's House offers a number of poignant commentaries on the exigencies of the human heart that become desperate needs in the face of societal rigidity. 

Krogstad, due to a single mistake, is ruined and has little hope of recovering his dignity or his livelihood. He says as much to Mrs. Linde in the play's final act. 

"When I lost you, it was as if all the solid ground went from under my feet. Look at me now—I am a shipwrecked man clinging to a bit of wreckage."

Mrs. Linde applies the same metaphor to herself a few lines later. When Nora leaves her husband and children, we then have three individuals who have been failed by their culture in one way or another. Yet, the play is hopeful. There is a chance at self-fulfillment for each of these characters and, importantly, they set out on a course of action to pursue that fulfillment.
