this time around has made Norma a woman who was treated terribly by the studios and the fans who have forgotten her. Unable to deal with that reality she has clung to this ridiculous thought of making a return (enabled by Max). So from the moment she first descends the stairs to grieve the death of her pet - you see this tragic character. And because Joe isn't being played as manipulative as he was in the film and the original - even he's somewhat sympathetic.
That's why in this production the New Years scene seems less like the suicide attempt being staged as an attempt to make Joe feel trapped and more real... Norma starting to recognize no one really loves her causes her to slit her wrists. Joe feeling responsible and some affection for her plight causing him to stay.
It's kind of the frog being put in a pot of water, and doesn't notice its' getting hotter and hotter as the heat is turned on to eventually boil him to death. Which makes the finale that much more dramatic and thrilling. Honestly - this production is a vast improvement over the original production and does enhance or take the story in a bit of a different direction than the film - which should be the point in musicalizing a film. I can't wait to go back to see this again.
