BroadwayConcierge said: "For Ambrose's Eliza, it felt like we had reached the end of an extraordinary arc for the character. With Ambrose, the vulnerable, ambitious, tender Eliza that we started off with in "Loverly" had evolved into a woman of immense resolve, dignity, and strength. A woman no longer seeking a change in her station, but who is now grappling with how to come to terms with a man who has changed her life profoundly and yet challenges her core. As I said before, I was nowhere near as moved during "Without You" by Benanti's Eliza, who did not really seem to have been as affected or changed by everything that had happened until that point."
I've never seen a live production of this show, but on the page and in the film, I personally find Eliza's arc to be somewhat circular, to mix the geometry metaphors. And not necessarily in a bad way. Towards the start when she asks for lessons, it seems to me that she already then has the self-regard to believe that she can rise up if given the opportunity, and she already recognises that Higgins doesn't treat her well enough. She temporarily loses that sense of self-worth, but (arguably) regains it by the end, along with having gained new skills that will give her practical power to make her way in the world. She succeeds in transforming... back into herself. I haven't pored over every nuance of this show - or this thread - so was curious if any others see it in this way? It could be that it's all in how it's played, of course.
