Just started watching this show before Christmas, seen about 3 episodes so far. Have they ever actually explained what the deal is with the characters talking to the camera? At first I just figured it was like Malcolm in the Middle or Saved by the Bell, only more frequent, but then I got really curious watching "The Injury" episode last night when they wouldn't let the cameras into the CAT scan room. Is there more to that aspect of the show that I'd understand if I'd been watching from the beginning?
