"Thor's Hammer"
From here on, Season 1, I think, begins to pick up. This is one of my favorites of SG1's first year. Here we have the introduction of the Asgard in the series, even though we don't actually get to see them until Season 2's direct sequel to this particular episode. But, we have the mentioning of them. We also have the introduction of the Unas. James Earl Jones, by the way, was a great choice for the voice.
