The Wizard of Oz as a Metaphor for Recovery

I am working on this to use as a group activity and would love input.

Dorothy Gale runs into problems with Miss Gulch who insists on taking Dorothy's dog Toto off to be euthanized because he's been chasing her cats. (Stressor)

Toto escapes, but since Dorothy's Aunt Em and Uncle Henry were going to let Toto be euthanized, Dorothy decides to hit the road. (my way or the highway. run from your problems.)

The good witch Glinda appears and advises her to revisit that "hit the road" plan and make her way to the Emerald City (Reconsider what she is doing and choose a path toward a rich and meaningful life)

The Yellow Brick Road points the way (they choices we make that help us move toward a rich and meaningful life (including the choices we make at forks in the road)and leads her to a motley crew:

A Scarecrow in search of a brain (Thinks he is too dumb to be useful. What does he do along the way that shows he really is useful?)

A Tin Man in need of a heart (Thinks having a real heart would make him whole. What does he do along the way that shows he already has heart?)

A Cowardly Lion looking for a little courage (Can't be the King of the Jungle because he is trapped by his fears. How does he show his courage along the way?)

They get to the Emerald City after dodging some threats from the Wicked Witch of the West, a very scary Wizard demands the witch's broomstick in payment, sending them off to the deep dark woods and a passel of flying monkey minions. (Handling set-backs)

Dorothy gets dragged back to the witch's castle with her friends in hot pursuit. They save her just before the sand runs out (literally), but the witch corners them and prepares an uncomfortably ironic demise for each one.

Dorothy responds by throwing a bucket of water on her—though actually she just wanted to save the scarecrow after the witch set him on fire—and the villainess's secret weakness is revealed. (Wow, troubles do melt like lemon drops out here.) The witch's henchmen were apparently getting ready to give her a World's Worst Boss award, and set the foursome free with a hearty "thank you so, so much!" and a joyous rendition of "Ding, Dong! The Witch is Dead!" (There are two sides to everything)

They take the broomstick back to the Wizard, who suddenly gets a case of the Wait-A-Minutes instead of granting them their hearts' desires. They get pretty angry at him (having just iced a Wicked Witch, the Wizard's whole giant-head-and-billowing-fire routine doesn't look all that menacing anymore), and Toto reveals a nervous little man running a giant Wizard apparatus.

As it turns out, he's the Wizard: a huckster with no powers and abilities, surviving on his ability to put on a great show and nothing else. (The inner critic)

He then produces a series of objects designed to make the gang feel better: a diploma for the scarecrow, a heart-shaped watch for the Tin Man, and a medal of valor for the Lion and informs them that they had these things all along. (They were just stuck in their beliefs that they did not)

The Wizard agrees to take Dorothy home in a balloon. Sadly, Toto's cat-chasing habit gets the better of him, and Dorothy gets out to chase him. (What things in your life are like Toto, a pain in the neck, but totally important?) By the time she gets him, the balloon has broken loose and goes flying off into the sky without her.

All seems lost until the appearance of Glinda, who reveals that the magic shoes can take Dorothy home whenever she likes. (You have the power to get back to what is important to you) She says a tearful good-bye (while classily declining to mention that Glinda could have told her this at the start of the movie), and then returns home to find friends and family waiting for her. (She realized that she could not be truly happy at the emerald City without her family)

What other metaphors do you see in the movie?
