"Boyhood" (Richard LINKLATER) Patricia Arquette as the mom of two kids over 12 years is movingly real and natural as the mother who shepherds her children through the breakup with their father (Ethan Hawke) and two turbulent marriages before emerging as a professional successful single woman--with an empty nest. Arquette's money scene comes near the end, when her son leaves for college and she admits, "I just thought there would be more." Arquette is a key window into this accessible and identifiable movie, for parents and children alike.
