"Dreamgirls" dramatically demonstrates that no man should ever attempt to assemble a superstar female pop trio because odds are the women will still you treat you like an ass. When the movie begins, Effie (Jennifer Hudson), Deena (Beyonce Knowles), and the other chick nobody cares about are at wit's end. They can't even win a local Detroit talent competition. Effie talks about quitting.
Then Curtis (Jaime Foxx) comes into their lives. He takes the group from nothing. He risks his Cadillac dealership to record music. He then sells the dealership, and risks that money on poker games and boxing matches to have enough cash to bribe DJs to play the girls' music. Curtis then leverages his radio clout to give the girls access to lucrative clubs that would never have hired them before. Then Curtis tells Effie that Deena should sing lead and all the sudden he's an a-hole??
Why? Because it isn't enough for Effie to be a star, she has to be the star?? Isn't it more like maybe Effie is an egomaniac who should be grateful she's not still living with her mother who won't let her out of the house at night? Hey Effie, if you're so great, how come you're not a star on your own?? I didn't see anyone clamoring for your solo work in the eight years you were performing before you met Curtis.
And if Effie insists on being in the spotlight, is it really too much to ask that she be proactive and do some sit-ups since after all she is in show business? Curtis, gentleman that he is, attempts to keep Effie in the group despite her lateness, drunkenness, and aberrent behavior. Eventually, he can't take it anymore and attempts to extricate himself from what is clearly an abusive relationship. Of course, Effie has the nerve to turn it on him and goes off on one of the most psychotic break-up rants you've ever heard, demanding, "You're gonna love me," for about ten minutes. A class act, Curtis refuses to participate in this clearly dysfuncional breakdown, and walks away.
Effie then hides the existence of their daughter from Curtis so she can selfishly raise the girl alone in poverty, instead of providing the youngster with the resources she will need to get ahead.
An emotional rock, Curtis pulls himself together, taking Deena and making into one of the biggest stars on the planet, landmark territory for an African-American woman. He plans to produce a movie with her starring as Cleopatra, a great Black female heroine and borderline goddess. Is Deena thrilled? Of course not. She's furious she can't star in an Indie movie playing a junkie who blows a truck driver. She leaves Curtis.
Is this a happy ending? "Dreamgirls" hedges on this point, leaving the viewer unsure of whether Curtis had a prenup.
