The second season of the shortly lived Friday-night drama Joan of Arcadia arrives on DVD this week. On this whimsical CBS dramedy with mystical overtones, Amber Tamblyn starred as Joan Girardi, an awkward, underachieving teenage girl who happened to receive visits from God, who showed up in various mortal guises. Also on DVD: season 1 of Bones, Criminal Minds, and St. Elsewhere; season 3 of 7th Heaven and season 5 of Ellen.
