Although some of the acting is a bit slack in places, The Wiz is all about Charlie Smalls' disco songs, the superfly costumes and the gorgeous dancing. Even so, some of the protagonists are excellent. MTV star Kat's loose-limbed scarecrow, Edward Baruwa's Tin Man dude and Nigel Roche's sweet, effete Lion steal the show in their search for brains, heart and courage while Jia Frances's Dorothy grew in stature the further she progressed down that Yellow Brick Road.
