I have Joan of Arcadia on DVD because it isn't currently available on Netflix. I don't always plan on posting what I'm watching, but I always felt that this was an unfortunately short-lived series that summed up nearly everything it meant to be a teenage girl.
The characters are sensitively drawn with subtle intricacies and back stories which are slowly introduced. Each character begins as a stereotype: the jock, the nerd, the outcast, the caring mother, the tough-guy father, the artist, the rebel... and then they move away from these archetypes into rich personalities as true to life as I have found in the best young adult books.
A mixture of fantasy, philosophy, and the realities of teenage life, Joan of Arcadia is the definition of film as literature... if only there were seasons 3, 4, 5, and beyond.
