It was a good episode. It didn't rush things too much, but unfortunately, it moved along too slowly.
The story was too thin to drag it all out into 42 minutes. They kept repeating stuff and dragging scenes out a bit with sneak-em-up-footage and running-away-from-footage.
But all in all, a good episode that conveyed many emotions. However, it was a bit obvious. Once that 2nd in command woman started acting funny, you knew there was something wrong. And then when they found a mummy, you knew in a flesh a Wraith had replaced her inside of the virtual reality (and you knew it had to be her. You didn't even have to check her clothes).
