”A Roswell Christmas Carol” (2000)
For Max (Jason Behr), the holidays mean coming face to face with a moral conundrum: when to bust out the superpowers. While Christmas shopping, he sees a father sacrifice his life to save his daughter from a car accident. Dead Dad then haunts Max, Dickens style, demanding to know why he didn’t use his alien skills to help him. In the end, Max does use his gifts — at a children’s hospital ward. It’s all sweet and touching…and would almost be cloying if Katherine Heigl weren’t spinning around in a holiday dervish as Isabel, the ”Christmas Nazi.”
