This is botched in a hundred ways. Factual errors aren't the point - all biopics play with the truth for dramatic reasons, but the story here is inept. The story starts and ends nowhere, investing none of the events with significance. There's no sense of drama, no building of tension, no interesting characters, nothing but Diana Ross bumbling around the sets looking awkward and projecting little personality. How does one re-create a 1920's Harlem whorehouse and manage to make it look as interesting as a Motel 6?

And the singing - there's no doubt Diana Ross has a voice, but she doesn't display the slightest connection with the material. No one could imitate Billie, but one would hope for some kind of interesting interpretation to help pull off the impersonation. But Ross phones in the tunes, with little feeling or style.

Most of the other characters are cardboard, with Richard Pryor doing the weirdest role of his life as a timid, comical piano player.

Absolutely unwatchable for anyone but die-hard Diana Ross fans, and for Billie Holiday lovers and movie buffs, sheer torture.
