One thing strikes me every time I watch this episode, and it occurs near the beginning. There are two 4-person teams, one from the US, one from Russia. Daniel manages to open the ziggurat door, and guess what? All eight people go inside. Has SG1 not learned ANYTHING from their various missions? You don't go into a strange building without having an exit strategy. They should have left one person on the outside, with the code to open the door, in case anything happens. (I bet those Russians wished they'd done that... right before they were past wishing for anything.) After all, what good is knowing how to gate back to your home planet if you can't get out of the building you went to visit?
