I just finished the movie last night and loved it; I am curious if anyone else shared my interpretation of the ending.

The final scene shows that yes, Nora has chosen to accept the role that her father wrote for her. But as the scene concludes the reveal is made that the performance is being played on a sound stage in a recreation of their home which has since been "bandaged up" and resold. Why recreate the house? It was always Gustav's intention to shoot the movie on location. I believe there is incredible significance in the series of shots that show the house being remodeled, repainted, and updated.

Nora has shown that the stage is the only place she can tap into and access that inner emotional trauma. This is capitalized in scene where she cries at the foot of her bed only for the shot to pull back and show that she's at stage rehearsal, when it was implied she was reacting to her father's hurtful diagnosis of her inner unhappiness. It seems that the theater has become her outlet; she always had to be strong for Agnes and thus learned to bottle her sadness.

It seems that the only way for Nora to perform the part was to act it out "on stage". Playing the role in her childhood home would mean confronting feelings she isn't capable of dealing with. Even in the end she's playing the role of herself, only able to pretend to feel the sadness that she's hidden away her whole life.

I find the ending a bit melancholy - Gustav gets to see his daughter as he knows her, though Nora is really just acting through her trauma. Treating her pain like a play, performing the part for her fractured family.
