Modern cinema is also brave enough to show the failure of blending. Not every story has a happy Thanksgiving. In The Kids Are All Right (2010), the sperm donor (Mark Ruffalo) enters the lesbian household of Nic and Jules (Annette Bening and Julianne Moore). The film is a brutal look at the "intruder" dynamic. While the kids initially bond with their bio-dad, the equilibrium shatters. The film doesn't demonize the donor; it simply shows that blending requires the consent of the gatekeeper —the biological parent who feels threatened. When Nic tells the donor, "You have the privilege of not having to be a parent," she articulates the resentment that festers in many real-life blended homes.
