The whole thing about Mila Kunis going crazy jealous over Oz and wanting to murder him just because he didn't fall for her. It's like, she showed him the way out of the woods for 5 minutes, and now he's supposed to marry her or something. She literally went bonkers over nothing but thin air. I was sitting there thinking "okay ...?"
To be honest, Oz was Theodora's 1st everything. He took all her firsts in one night. Her first dance, kiss, and virginity.
As for what Oz did wrong, his womanizing. if he didn't care about Theodora, he shouldn't have flirted and slept with her. Same for all his other jump-offs. Oz is an *beep* who does things only for himself, and his own gain, included banging and dumping women.
And why the Wicked hated him so much, the apple gave her knowledge. She lost her naivety, and saw what kind of man Oz was, and what he did to her, which was deceive, defile, and dump her. So, I would guess she wants revenge for being treated as his pawn. because all he did was use her.
As for Theodora, I believe it was a crush she had on Oz. Oz being the first man Theodora's formed anything with, she was naive and didn't know better.
But, it being her first, and being a complete blow out upset her. Lots of girls would feel angry, or hurt.
People grieve in different ways. And hell, Theodora was only upset a few hours. She was crushed. She moved too fast, and got with the wrong guy. And chances are, she would have gotten over it. People don't get over something horrible happening in 2 hours. But, while her grief was fresh, and just hit her, Evanora swooped in, manipulated her more, egged her on, then gave her an evil apple.
Theodora only had a few hours to be upset, if not just one hour. So, of course her hurt was at it's strongest there. Because it was still fresh.
Now, she accepted the apples, because she thought it was take away her heartache, and she wouldn't care about what happened. But again, this hurt is fresh. It's just happening over the course of an hour. She just didn't wanna be sad anymore.
She didn't know her sister was evil, or that the apples would make her evil. When she found out those 2 things, she was horrified.
I can understand if people think the whole love/jilted part is corny. But, Theodora didn't become wicked and evil because of that, at least not willingly. People act like when she found out about Oz, she went crazy and started killing or something. Oz upset her. She became wicked because of her sister.
Even when she was upset about Oz x Evanora, and Oz x Glinda, she just broke a mirror, and it seemed that was due to herself. When she cries, she says "You fool, serves you right", before smashing the mirror.
So, she was apparently upset with, and ashamed of, herself, because as Evanora told her, Oz didn't say she'd be his Queen. She just assumed it, and treated is as fact. So, she realized she moved fast, and assumed too much too soon.
So, while upset that Oz didn't want her, I think alot of her anger, and hurt was with herself for allowing herself to fall into that position. Falling for all the flattery and nice words she'd never heard, then it turns out, all they were was just that. Nice words with no feeling. Thus she allowed herself to be used and thrown out, as opposed to taking things slower.
Oz wasn't worth perusing at all, by any woman. Clingy, or Indifferent So, it's made worse when a naive girl fall for the bad boy, because she's easier pray. So, even if Theodora didn't move so fast, Oz still wouldn't have wanted her. But, she didn't know that. It seems she blames herself.
Theodora seemed like the perfect pray. A beautiful girl who's naive, and, possibly, has low self-esteem
And when she bit the apple, and her eyes were opened, she was horrified. So, even with what happened with Oz, she didn't want to be wicked, nor kill anyone. She transformed unwillingly.
The whole ordeal with Oz made her vulnerable, at which point, Evanora swooped in.
I still think it was silly and poorly executed. Not necessary at all in the story. The movie would have been better off without it.
