I watched the movie Big Girls Don't Cry... They Get Even. This movie stars Hillary Wolf (Home Alone), Ben Savage (Boy Meets World ; Girl Meets World), and Jenny Lewis (Life With Lucy).
A young girl's parents divorced when she was eight. Now, at thirteen, she lives with her mother, her stepfather, two stepbrothers, a stepsister, and a half-brother. She used to visit her father, stepmother (third stepmother) and half-sister, but now *another* divorce is in the works, so Laura visits her father and his pregnant girlfriend -- who's only six years older than she is. When the girl gets fed up with her quirky, dysfunctional family, she runs away from home, causing all of them to spend time with each other.
I give this movie 3 out of 5 stars.
