These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Draco in Leather Pants: Alright, show of hands who has read fanfiction involving Theodora getting redemption, even though the film shows that this is literally a physical impossibility? Hilariously enough, Mila Kunis does wear leather pants in this movie.
Ensemble Darkhorse: Joey King as the China Girl is often cited by critics as the best character in the movie.
"Funny Aneurysm" Moment: When Glinda reveals Evanora to be the real villain of the story and that Evanora had tricked Oz (you know, like he did back in Kansas, only with parlor tricks instead of real magic), suddenly Oz's interactions with Evanora become Laser-Guided Karma.
Genius Bonus: Oz's love interest back in Kansas, Anne, is going to marry a man named Gale. Many sources give Dorothy's surname as Gale.
A number of people are already condemning the film simply because it contradicts/has nothing to do with Wicked, while others are complaining that they got Elphaba's name wrong. On the flipside there are fans of Baum's book that are tired of people treating Wicked like canon, and so are happy to see an alternative prequel.
Also, people claiming that Oz later ordered Theodora's death, when in fact the Wizard only does so in the original book. In the MGM film, which this movie is set in continuity with, he only asks that Dorothy steal her broomstick, with the Scarecrow only assuming that they'd have to kill her to do that and Oz himself clearly doubting that they'll succeed or even attempt.
It is also getting a lot of hate simply because it is a prequel.
In addition, in that particular episode, Donna was mortally offended that Jackie imagined her as the Wicked Witch of the West. In Oz the Great and Powerful, Jackie is the Wicked Witch of the West.
There's a lot of parallels to Tim Burton's Alice in Wonderland: both are big-budget 3-D Disney movies about people who go to a fantasy land that was All Just a Dream in their respective original movies, discover they're prophesied — by name — to save the land from a pair of warring, psychotic sisters but the Big Good on their side is forbidden to kill and the Big Bad(s) are exiled in the end.
Jerkass Woobie: You will want to reach through and hug Theodora...but after seeing Evanora corrupt her, you wouldn't be too unjustified in keeping your distance
Les Yay: Some see it between Evanora and Glinda, and also Theodora and Glinda. They both seem obsessed with caressing Glinda's face and calling it pretty out of...jealousy. Yeah, jealousy. Sure.
Moral Event Horizon: If Evanora hasn't already crossed this with the murder of Glinda's father, she crosses it when she tricks Theodora into losing her heart and all her goodness, and becoming a witch more wicked than she is. Even she realized after this act that she had taken her quest for power too far and that there was no turning back.
Again, Theodora. It's rare that a performance can be so hilarious and terrifying at the same time, but Mila Kunis somehow manages to pull it off.
She is trying to fill the pointed hat of one of the greatest Large Ham roles in cinema.
Oscar's performance as "The Great and Powerful Wizard of Oz" is such over the top scenery chewing that it would plunge headlong into Narm territory if it also didn't happen to be his truly epic victorious Moment Of Awesome against the wicked witches with Rule of Cool on his side.
Relationship Writing Fumble: One of the most vocal complaints about the movie is the writing of the relationship between Oz and Theodora. Theodora's Start of Darkness was a result of Love Makes You Evil...but the two of them were barely on-screen together at the same time to develop such deep feelings for each other. The rushed nature of the development made it stand out more.
Oz and his party using smoke and mirrors... literally... to create the "Wizard of Oz" persona for Oz.
Stop Helping Me!: Oz soon discovers that letting Finley in on his secret leads to being loudly announced as "the totally genuine Wizard".
Strangled by the Red String: Oscar and Theodora. A major part of the movie's plot revolves around her falling in love with him, and then turning evil after she thinks he's betrayed her. But this falls short when you realize that Oscar and Theodora have only known each other for a day or two before he leaves the Emerald City and they don't see each other again until after her Face-Heel Turn. Despite this, she's already talking about how she'll be his queen and they'll rule Oz together, and completely breaks down when she thinks he's cheating on her. It's also not entirely clear how far their relationship went to begin with and whether they actually slept together or not, which can make Theodora come off as a Clingy Jealous Girl or a Stalker with a Crush.
The reason Theodora turns evil can come off as this. Someday, Oz will (in the original book) ask a little girl to murder his psycho ex-girlfriend.note Although, whereas in the book when she does kill the Witch it was a deliberate reprisal by Dorothy for trying to steal the silver slippers, in the 1939 movie Oz just asks for her and her friends to get the Witch's broomstick and Dorothy slays her completely by accident while trying to douse the fire that the Scarecrow had caught.
The movie as a whole feels like a mean spirited anti-feminist flic (ironic, given how L.F.B. was a feminist himself), with the female characters all either irrationally overemotional or glorified madonnas. To say nothing on how they all need a man to save them. note (Exactly the opposite of the Oz books, who were written in the beginning of the 20th Century and much more progressive). According to Word of God, this is partially intentional, as he wanted to create a fairy tale with a male lead. Furthermore, two of the witches were Doomed by Canon to become evil and the movie makes it quite clear that Theodora is not acting on her own free will.
The two actresses playing the "bad" witches—Mila Kunis and Rachel Weisz—are both Jewish brunettes, in contrast to the blonde Norwegian-American Michelle Williams as Glinda, which is another can of worms altogether.
Headstrong as China Girl is, your paternal/maternal instincts kick in when she's onscreen.
The girl in the wheelchair who China Girl is based on. It's heartbreaking to see her belief in magic crushed after Oz reveals to her that he can't help her walk again.
Frank, Oz's assistant back in Kansas. He's devoted to Oz despite Oz being an outright Jerkass to him. And then he watches Oz get sucked into the tornado and we never hear from him again.
Glinda. Between having her father killed, being framed for his murder, and getting tortured by the wicked witches in the climax of the movie, she's been through alot.
Theodora. A kindhearted, young, innocent girl who only remained neutral to keep peace between two feuding witches and in Oz. She's tricked into becoming evil against her own will by her own sister, who exploits her passionate love for the hero. She clearly is under the influence of magic while evil, and yet the people of Oz hate her, unaware of all this.
