I hated her for the most part during her time on the show. She kind of served as the Regina of the final season, which they wanted to be a "fresh start" and boy did that not work out in ABC's favor as the final season was the last of the "new" story.
We already saw a stepmother of another Cinderella, but she was a little different. They also combined her story with that of Rapunzel which I thought was a little dumb.
After the final curse, she serves as a thorn in everyone's side. Being the de facto leader of this new sub-town in Washington state.
But she dies taking her daughter's place to save Lucy due to some weird witch curse or something. I never saw that the fact she actually loved Lucy or that she'd do so much for anyone besides herself coming to be honest.
