All I can say about this episode is this: ABOUT DAMN TIME!!!!!
I (and lots of Atlantis fans) have been waiting for the backstory episode for Sheppard. We finally get it. And now that it's here, it makes complete sense and fits with his character. It also reinforces the notion that only Joe Flanigan can be Sheppard and no one else.
I thought this episode was great. I liked how they took an old idea, the "everybody's gone bonkers" routine and made it new. The twist was using it to develop backstory on a character that needed it. I thought the writing was excellent on this episode and the acting superb. This REALLY has been the year for Atlantis. I do now see, with this episode, where people are debating: Sheppard-Weir (or Shweir) or Sheppard-Teyla (Sheyla). I'm leaning more towards the former than the latter but either is nice. Teyla has that way of getting to Sheppard. They should develop this relationship more, like what was seen in this episode.
