All I will say about the as ever abundant commentaries is that it is once again great to see a cast member on a commentary, something not so rare for the Stargate cast. The only other extra on this disc is a featurette, "An Introduction to Ben Browder". this gives a deep look at Ben Browder, his attitude to stunts and his character of Lt. Colonel Cameron Mitchell. While both interesting and amusing, I do wonder why this geature is on this particular disc, way after Mitchell has been integrated into the team. I can't help but feel that this feature is made more for the first disc as we are introduced to a character we are by now very familiar with. In spite of this it is another great disc and has an always fun alternate universe episode.
