SEASON FINALE: This series, the NBC spiritual predecessor to such heartwarming family dramas as Friday Night Lights and Parenthood, concludes its first season with an episode that manages to wrest emotion even out of its flashback scenes, though we know how they will, and won’t, turn out. Credit the writing… and the acting, including that of singer Mandy Moore.
