I think this episode is one of the stupidest ever. All those brilliant minds and no one even thought about beaming the people on the other side of the planet where they would be safer for a bit longer, until they would come back after them. The Daedalus didn't even have to move in order to do this. And leaving the children and women last with Teyla and Ronon for dramatic purpose was incredibly stupid. I couldn't help myself laughing through more than half of this episode.
Season 2 of Atlantis had about 3 good episodes. I'd give the whole season a 4/10. It was extremely dissapointing.
