Sparkle

 
Sparkle tells the story of the title character; Sparkle, (Jordin Sparks) the youngest of three sisters and a music prodigy who struggles to becomes a star while overcoming issues that are tearing her family apart. Sparkle is from an affluent Detroit area, naive to the unexpected experiences her new life will bring as she and her two sisters blossom into a dynamic singing group during the Motown-era. Whitney Houston will play the trio's mother (Emma). Mike Epps plays a wealthy comedian named Satin, who woos Sparkle's sister into a drug-filled abusive relationship on their way to the top. During her journey, Sparkle endures the trials and tribulations of fame but fights to rise through the ranks of the music business.

I made it 25 minutes into this movie before not being able to take it anymore.  It's like a homemade rehashing of Dreamgirls.  It's pretty much crap. 

I wouldn't recommend anyone ever bothering with this.  It wasn't even worth a 26th minute of watching for me.
