Not bad! In the earliest days of Muppet literary adaptations, such as "Hey Cinderella!" and "The Muppets' Frog Prince," Kermit would be the host and brand-new Muppets would be created for the production, some of whom would be added to the Muppet "pantheon." "Frog Prince," for example, introduced the world to Robin (the title enchanted prince, though the character later became Kermit's nephew) and everybody's favorite ogre, Sweetums.
These shows were 1-hour specials. By the time the Muppets were doing feature-length adaptations, beginning with "The Muppets' Christmas Carol" and "The Muppets' Treasure Island," so many Muppets had been added to the stable of performers that they wound up in major roles with few new or story-specific characters being made (exceptions being the three Christmas Ghosts).
Either formula has its good points and bad points, but I really think the better tack to take with a Muppet adaptation of "Wizard" would have been to do it the old-fashioned way, with new Muppet versions of the main Oz characters, with existing Muppets in supporting roles.
If I may make bold, here's how I'd have done it: I'd have had Kermit appear at the beginning as L. Frank Baum, telling the story to a mixed group of human and Muppet children. He would then act as voice-over narrator for the rest of the show.
I would have cast Dakota Fanning as Dorothy (and I say someone still should before she grows up) and had new Muppets made specifically to play the Scarecrow and the Tin Woodman. There already is a Muppet Lion, one of those costume/puppet combos; he sang a duet with Sylvester Stallone on "The Muppet Show." Toto would also have been a new creation.
As for those already known, I'd have cast the old wardrobe lady from "The Muppet Show" (I can't remember her name) as the Good Witch of the North, Miss Piggy as Glinda (on the premise that she insisted on playing the part) and Taminella, the witch from "Frog Prince," as the Wicked Witch of the West.
As in the movie that they did make, Scooter would have been the Guardian of the Gates and Sam the Eagle would have been the Soldier with the Green Whiskers, only he'd actually have the whiskers (or feathers, I guess...) I'd have appointed Gonzo to play Boq the Munchkin and Fozzie Bear to play the Wizard.
As for Aunt Em and Uncle Henry, I'd definitely have them played by human performers, though I've no solid idea who. Any offers?
Now, FINALLY getting to "The Muppets' Wizard of Oz" which actually did get made, I found it on the whole enjoyable, but as has been the case with a lot of folks here, Pepe the Prawn as Toto got real old real fast. I like Pepe, but only in small doses.
The updating was a surprising touch given that the two previous Muppet literary ventures, "Christmas Carol" and "Treasure Island," were set in their proper historical eras (anachronisms notwithstanding). Certainly a teenaged Dorothy working at her aunt and uncle's cafeteria is as plausible as a 24 year-old schoolteacher Dorothy, as seen in the movie version of "The Wiz." But just like that movie, the all-too-modern Land of Oz was a bit jarring.
It wouldn't have mattered so much, only Miss Piggy as Tattypoo did say that Oz wasn't civilized. So how does she explain the TV's and computers and such? Having said that, the Wizard's use of holograms and VR was a clever modern twist on his old sideshow trickery.
Ashanti was delightful as Dorothy, and despite the um... outfit she got at the Emerald City (which was a parallel with the dress the literary Dorothy got), she always maintained that air of wide-eyed innocence which is essential to the character. The way she interacted with the Muppets was wholly natural, and she was a good solid rooting interest.
Kermit, Gonzo, and Fozzie did do a good job in their roles, I have to admit, and Kermit especially. The ingratiating personality given him by Jim Henson and so wonderfully maintained by Steve Whitmire suits the strawman-- er, strawfrog perfectly. Gonzo and Fozzie appeared as the Tin Man and the Lion respectively in a Muppet special saluting the movies some years back, so they seemed comfortable in the parts.
Then there's Miss Piggy as the Four Witches, and differentiating their personalities remarkably well. And though most folks here seem to hail her WWW, I liked her best as Tattypoo.
I was pleased to see how much of the book did get adapted, and delighted with the addition of bits that the general public probably wasn't aware of, like the SILVER shoes, the Kalidahs, and the various guises of the Wizard (even though the scriptwriter did mix them up unnecessarily). I also thought the amalgamating of the Munchkins with the Field Mice-- er, Rats was innovative.
The movie could have done with at least two more songs; there was a disappointing dearth in the singing department, especially since this was a Muppet production. I also thought that, even though it was true to the book, the scene of the Scarecrow being ripped apart and the Tin Thing being demolished was too intense for the very little viewers.
Will I buy the DVD? I think so; there's certainly more I liked about it than didn't. But I do long for the day when someone (maybe Hallmark) finally delivers that definitive, faithful adaptation of "The Wonderful Wizard of Oz."
Until then, there's plenty of good "Oz" out there, and the Muppets' version can definitely be included among it.
