In (and out of) the Motown groove
The challenge in reviewing Motown: The Musical is to be honest about its two most prominent components. The first is the clunky, self-aggrandizing book by Motown founder Berry Gordy who, at one point, has Diana Ross bat her big eyelashes and compare him to Martin Luther King Jr.. He also depicts the first time he attempted to sleep with Ross as a dismal failure, but when you're in bed with a pop legend in the making and you're writing the script, you can have her tell you everything will be OK and then sing "I Hear a Symphony" to you. It should be funny, and it is, but it's just as cringe-inducing.
The other component, and this is far, far more important, is the Motown music itself.
