OK, so I watched the first few episodes of StarGate Atlantis, and I liked what I saw, and thought the whole thing about them being out of contact with Earth was neat, but I ended up missing a good portion of it. There’s a marathon of it on TV now, and it seems they have their own Prometheus style Battlecruiser, complete with fighters, and are in contact with Earth, and something about Atlantis almost being destroyed.
In short, it seems I missed something. Fill me in?
