The concept of the nuclear family is now something of an outdated notion. With children now found in a wide array of living situations -- single parents, gay parents, adoptions, etc. -- the "ideal" of a child being raised by a mommy and a daddy is shifting, with a newer idea of just two good parents -- whomever they may be -- being of the utmost importance. The film world is slowly beginning to recognize and write stories that reflect the changing times. Of course, "The Kids Are All Right" is one of the best movies to present an unconventional family, while "The Switch" represents what happens when you try to approach this kind of thematic material without anything to say. Jennifer Westfeldt's ("Kissing Jessica Stein") latest effort behind the camera, "Friends With Kids," finds the actress/writer/director oscillating between an intelligent look at modern relationships and a conventional rom-com, to mixed results.
