We’re just going to have to admit it. The resurgence of live musicals on TV has been nothing short of daring and often mind-blowing. But while production levels can vary greatly between these live TV events, it’s the ensemble itself that often makes or breaks a production. So we couldn’t help but enjoy the delightful fun of “The Wiz Live!,” a spirited production buoyed by an incredible cast that included Uzo Aduba, Mary J. Blige, David Alan Greer, Queen Latifa and Common. Don’t get us wrong: Other nets have given us great ensembles (a quick shout out to Fox’s “Grease” is called for here), but the cast of the “The Wiz Live!” brought the show home with an unsurpassed jolt of nostalgia and newfound joy. Their outstanding performance was more than enough to make this retelling-of-the-retelling of the “Wizard of Oz” as irresistible as that Yellow Brick Road.
