After a fairly brief hiatus (only 4 months) Stargate Atlantis returns to the SciFi channel with all new episodes starting on July 11th. Now entering its fifth season, the show is reaching a turning point thanks to a number of off-season cast changes. First and foremost in is the replacement of Amanda Tapping's Colonel Samantha Carter as administrator of Atlantis with Robert Picardo's Richard Woolsey. This is one year after Tapping replaced Tori Higginson on the show. It's an interesting turn of events since Woolsey has not been the most popular of characters in the entire Stargate franchise. And, as the character has never been a people person, there is bound to be some conflict between members of the Atlantis team and himself.
