Film wasn't good enough for a performance like Andra's. Lee Daniels just can't resist melodrama and camp, and as a result the movie is an incoherent yet somewhat still entertaining mess. And the dialogue can be cringeworthy at times; I doubt a FBI agent would've said "They say her song is the curtain call for the so-called "civil rights movement".
I'll give Lee credit on this though: there's a one-shot take in middle of the movie that's legitimately great. One of the best things I've ever seen in a Lee Daniels movie.
