Not for the reasons you think. This production, with its guy-in-a-lion-suit approach to character depiction, draws in the viewers, whereas the vile more modern film Return to Oz, with its photorealistic “whimsical characters” alienated the audience. I think the reason the original’s approach worked so well is the same reason black and white films work so well––they do not duplicate our typical experience of viewing the world. They require that the viewer meet them half way, and for that reason the viewer actively steps into the film, and becomes absorbed. When a film is literal, the viewer is essentially instructed to sit back and do nothing, and that immediate absorption doesn’t exist. With magic, if an audience steps toward you, you have them. Simple as that.
