This is great science fiction and I agree with all of the positive reasons written here. The cast is absolutely magical with an international quality that adds depth to the drama that unfolds. Torri Higginson is perfect in the role as Dr. Weir and to think further on this.......I don't see any weak characters in this highly interactive lineup. The development of Dr. Beckett from a background role to one of the front core characters was a good move by the executives of the show. Another big plus in Stargate Atlantis is the fabulous Bridge Studios facility in the Vancouver area and the wonderful forest backdrops. Southwest Canada is perfect for science fiction shows like this. This is a DVD set for all SciFi fans.
