It may be a bit hard to fathom why this is called "Bonnie's Kids" when the mother character "Bonnie" is dead before the movie even starts and does not appear at all, even in flashbacks. But this is no doubt a reference to the movie "Bonnie and Clyde" which this film at times certainly resembles. Two sisters are living with their drunken, brutish stepfather after the death of their prostitute mother. The older sister (Tiffany Bolling) catches the stepfather trying to molest the younger sister(Robin Mattson) and shoots him dead. The two go on the lam and end up at the home of an uncle, who owns a fashion magazine, but (rather incongruously) is also a vicious gangster on the side. The older sister goes to pick up a "package" for the uncle from a dimwitted private detective. They fall for each other and when they discover the "package" is a large amount of cash, they flee with it with two of the uncle's dangerous associate (Alex Rocco, Timothy Brown ) in hot pursuit. Meanwhile, the younger sister is seducing practically everyone in her uncle's household from his studly gardener to his lonely lesbian wife. The ending makes the finale of "Bonnie and Clyde" seem positively cheery by comparison.
This movie has a real early 70's atmosphere of bleak pessimism to it, much like "The Candy Snatchers", another cult film of that era starring Bolling. It isn't just the downbeat ending though, but the fact that ALL the characters are totally amoral and unsympathetic, even the supposed heroines. The two sisters are more than willing to use their sexy bodies to get what they want and they seem completely untroubled by morals or basic human feelings. After convincing him to steal the money, the older sister is perfectly willing to betray her private detective beau and run off with a lecherous traveling salesman to save her own skin. The younger sister, meanwhile, is even more callous: she drives one of her lovers to suicide and then just laughs when she discovers the body. In the end, she doesn't even seem to care about the fate of her older sister.
These sexy but totally unsympathetic heroine roles were pretty much the specialty of Tiffany Bolling. So, not surprisingly, she's pretty good here. This is one of Mattson's first movies, but she would go on to a brief exploitation career (i.e. "Candy Stripe Nurses"), and a much longer career in American television. In way she almost manages to "out-Bolling" Bolling here. She was still pretty young when she did this role, but nevertheless men (and lesbians) everywhere will no doubt be thankful that they don't have a malicious temptress like THIS for a stepdaughter. Director Arthur Marks, who also produced "The Candy Snatcher" would go on to do a couple influential "blaxploitation" movies ("Detroit 9000", "J.D.s Revenge"). I can't say this movie will fit everyone's taste, but one things for sure--they don't make 'em like this anymore.
