The firsts in SGU Stargate Universe

The body swap thing was the most interesting part, and was used very creatively in terms of science fiction.

SGU had so many firsts in space-based sci-fi tv:
• They had the first openly gay crew member as part of the main cast ("Wray", played by Ming-Na),
• they showed wheelchair-bound people, and how difficult was it to care for them, and also how they could reach success, if given opportunities;
• they had several episodes about ALS well before Ice Bucket Challenge;
• Music montages throughout the series, with topical songs strategically placed into almost each episode. This has never been done before in sci-fi, and was typically scarce on non-sci-fi network television.

And the awesomest incidental music by the late Joel Goldsmith.
