Many a summer we have done a marathon of TV watching focused on a single show. In the past we have done "House" marathon, "24" marathons, and one summer we did a marathon of watching the TV mini-series, "The Tenth Kingdom".
This summer we are watching one of the best TV series ever made, "Battlestar Galactica" (2004 to 2009) It is a superb drama with social and religious themes. We will miss it when it ends.
