* AlternativeCharacterInterpretation: An only moderately altered interpretation of Nora has the side effect of altering the entire play. In the conventional reading, Nora is a naive innocent who gets a harsh lesson in the world and grows up to move out. A wholly different interpretation is that we're actually seeing a plot involving several conspirators, organized by Nora, to break her tyrannical husband's hold. The Doctor being "ill" is a setup—he's fine and the card with the X through it is a signal he's ready for Nora to take off with him as they've obviously had a thing going on. Nils Krogstad's reasons for going along with the setup are obvious (knowing he's on the chopping block at work because of Torvald, he has nothing to lose and everything to gain revenge-wise) and Nora is also, more kindly, masterminding the reunion of Krogstad with his old girlfriend and her old friend, Christine, who's been the victim of a similar domestic tyranny. Nora is in fact a DiabolicalMastermind[=/=]MagnificentBitch orchestrating her husband's downfall.
** A less elaborate example: Nora is often portrayed as a naïve victim of a domineering Torvald, but she can also be interpreted as the HypercompetentSidekick of a ManChild who is totally oblivious to how much work his wife puts into maintaining the façade of security and respectability that lets him see himself as a self-made success.
* CrowningMomentOfHeartwarming: Krogstad's and Linde's reunion and their affirmation of how hard they will work in their marriage.
* MisaimedFandom: No, this is '''not''' a play about how evil men are and how terrible marriage is. It's more a play about how relationships fail when they're based on acting out social expectations instead of on mutual understanding and respect. Torvald and Nora never really ''know'' each other, because their entire marriage consists of them "playing house," acting out roles based on their assumptions about how the ideal Husband and Wife are meant to act. Meanwhile, Kristine and Nils are able to achieve a happy ending because they truly know each other, warts and all, and form a partnership according to terms that suit them as individuals.
* SomeAnvilsNeedToBeDropped: After the truth comes out about how Torvald doesn't really love Nora for Nora, she removes her proverbial mask and tells Torvald why she must leave him. After spending the entire play masquerading as an airheaded ditz whenever her husband's around, she suddenly shows him how serious and well spoken she truly is. If the effect is jarring, the message is downright radical considering the time when the play came out.
* WhyWouldAnyoneTakeHimBack: Averted. Torvald berates Nora viciously, then just as abruptly decides to forgive her because she is like a child and knows no better. She allows him to hug her and tell her how much he loves her, leaves to get changed - and walks back in with a suitcase to announce that she's leaving him.
* WriterRevolt: The "happy" ending written to appease the MoralGuardians only comes about because Torvald guilt-trips Nora into staying by way of "ThinkOfTheChildren"; and Nora considers this a FateWorseThanDeath.
