A classic of alternate realities. I can only imagine that if more people had watched this episode (actually, this whole season), the series would have continued. Definitely not a stand-alone episode, though. This requires watching the episode of Rodney and his sister (name escapes me) where they create the original reality bridge. In any case, an excellent exploration of Shepard and McKay's characters. Well worth the watching, and one of the best of any series' episodes of "playing with the storyline." Very sad the series ended after this. The writers/producers demonstrated the creative levels they could achieve in this story.
