New Arcadia arrivals include Will's controlling boss, Lucy (Annie Potts), Joan's "crazy camp" friend, Judith (Sprague Grayden), and enigmatic do-gooder Ryan (Wentworth Miller, Prison Break), who shares Joan's gift. Despite critical kudos and respectable ratings, Joan of Arcadia wasn't picked up for a third season, but its spirit lives on in such disparate shows as Medium, in which a woman communicates with the dead, and My Name Is Earl, in which a man goes around doing good deeds. This six-disc set features commentary by creator Barbara Hall, producer James Hayman, and writer Stephen Nathan. --Kathleen C. Fennessy
