The film is another story, but the show Stargate SG-1 is a boomer series because:

- In most of the episodes, the assumed leader is Colonel Jack O'Neill, who is literally a boomer and fits perfectly into the stereotype. The character's purpose is to show that positive qualities of boomerism win, while sarcastically dismissing the value of everything new.

- It's a patriotic military Sci-Fi that portrays the US military as mostly good. Reverence for the United States military is strongest with Boomers. Similarly, the theme of "American exeptionalism" is strong throughout the series.

- For a show made in the 2000s, Colnel O'Neill's consistent distrust of the Russians, contrasted with the relative openness displayed by other characters, is rooted in Cold War experience that strongly resonates with Boomers.

To be clear, I'm not saying any of this is bad. Personally I think it was a good show. Rewatching it today gives me nostalgia both for the show and the ideals of the era.
