Will the witch melt? That was the hot topic during a Langley family pre-Rep meal in Brindleyplace. She did. Brilliantly.
She couldn't have really melted, though, could she, reasoned our four-year-old in the car on the way home, because she came back on at the end for the clapping (there was, quite rightly, a lot of that).
Grandfather matter-of-factly explained about smoke and a slow drop through a trapdoor. It's like magic, said a drowsy Rebecca and promptly fell asleep.
For no dry technical analysis can really explain the spell of this latest Rep outing for Rachel Kavanaugh's production of the legendary book and film.
So let's just say yes, the company is uniformly excellent. Even the helium-powered Munchkins (a particular problem for me in the film) are heartwarming. Yes, the famous songs come over brilliantly, and the music (directed by Stephen Ridley) is great, with reeds work from John Graham worth a name check.
Yes, it looks wonderful thanks to designer Peter McKintosh and Mark Jonathan (lighting). The film-echoing monochrome Kansas and vibrant-toned Oz are superb, the circular sets are breathtaking.
Yes, the aerial work is spot-on, the projected film sequences are highly effective and provide a link with the world of the movie.
The choreography ( Jenny Arnold), couldn't be bettered - superb jitterbug routines, and the whole huge production simply rattles along.
The nitpicking critic wasn't happy with the non-period pedals on Miss Gultch's bike - modern orange reflectors on rubber. I only mention that to prove that I really was watching very, very closely.
So after all that I am left with a pleasant glow and the same conclusion as my grandchild - magic.
Running time: Two hours, 30 minutes. Until Jan 21.
