In this Chick Flick about a "reverse love affair," Merryl Streep has a few too many drinks with her ex, Alec Baldwin, at her son's graduation and sleeps with him. Their torrid evening romance leaves Baldwin wanting for more and Streep guilty about being the "other woman." Steve Martin, Streep's architect, develops a romantic interest in her while she gets consumed with guilt and agonizes over Baldwin's advances. Streep and Baldwin sneak around so the kids don't find out. But they eventually do and it all comes to a boil. It's Complicated. Baldwin steals the show with his coolness and antics. Martin is subdued and almost humorless. Streep's many emotional scenes reveal her incredible believability and her versatility.
