Oz rescues a wisecracking flying monkey named Finley (voiced by Braff) and a tougher-than-she-looks China Doll (voice of Joey King), and they become his companions on his mission. The quest gets much more complicated when they realize that the witch they've been dispatched to defeat, Glinda (Williams again), is actually the good one, while Evanora is the conniving spell-caster who killed Glinda's father, the previous king.
Glinda knows Oz is a selfish con-man, but she also thinks he might just have what it takes to rally the people to defeat Evanora and her horrible army of winged baboons, which are much scarier than the flying monkeys of old, particularly in well-rendered 3-D, and sure to terrorize young children.
Overthrowing the true wicked witch becomes even more daunting when Evanora manipulates her temperamental sister into becoming a green-faced crone, which Kunis turns into a worthy predecessor to Margaret Hamilton's scenery-chewing antagonist.
The mythology gets a bit murky, and the decision to have Williams and Braff play roles in both Kansas and Oz feels arbitrary. But Raimi grants “Oz the Great and Powerful” enough magic to carry the day, and even better, prompt families and film fans to reunite with Dorothy and the original “Wizard of Oz.”
