You can tell that this movie is low budget, but the premise is relatively believable and has a nice twist at the end. At times, it seems like a showcase of the music on the soundtrack, but those scenes aren't that long. There are a few very funny scenes (almost always the ones with Lavell Crawford or Buddy Lewis involved) but also some bad parts that seem like the actors were improvising poorly or just talking. All in all, if this movie is on cable for free or you see it for $1 on DVD in the store, it's worth picking up just to see the old Destiny's Child all together. If it's going to cost you more than $1 to watch it, I'd say save your money. The way that the cover art looks like something that's been photoshopped is a good indication of the quality of the film.
And if you somehow don't pick up on it, this is supposed to be a black parody take on The Beverly Hillbillies. Most of the Hillbillies characters have a double in this movie (Jed = Red, Ellie May = Pammie, Granny = Papa, Mr. Drysdale and his wife = the uppity neighbors, Jethro = Nathan etc)
