Visually stunning, but after everyone jumps off the plane I actually find this one a bit dull for some reason. Marina Sirtis is great, but the story never really gets going and there's a bit too much wondering about what is going on. I particularly don't enjoy the scenes in the submarine, despite Daniel's brilliant, "but it's Swiss!" line. Maybourne's appearance is certainly unexpected and pretty weird!
The episode marks the start of the big Russian storyline which runs through the rest of the show, and we find out what happened to our original Stargate, which is nice.
RATING: 7.5 out of 10
