If you’ve been a fan of “Star Trek” as TV series, movies and concept as long as I have, there’s probably not a ton of surprises in “The Center Seat: 55 Years of Star Trek.” But the 11-part documentary series, now streaming, is nevertheless mostly fun.

“The Center Seat” originally aired on the History Channel a couple of years ago – or at least three or four episodes aired. The rest never saw the light of day and the only on-demand episodes available were limited to those few episodes.

So it was cool to see the entire run of the show – which follows “Star Trek” from before “Star Trek” was even “Star Trek,” through the shows and movies and right up to and mostly including cursory looks at the current crop of shows in the franchise – appear on streaming services like Peacock and Amazon Prime Video. I reacquainted myself with the few episodes I’d seen and finished out the series.

Narrated by Gates McFadden, who has played Beverly Crusher since “Star Trek: The Next Generation,” the series is a little glib in the fashion of “documentary” series like “The Movies Who Made Us,” which are quick-cut, “funny” looks at films. With those type of shows, the interviews are edited into three-second sound bites juxtaposed with clips and images to create mirth.

“The Center Seat” doesn’t do as much of that as some of these pop culture docs and the substance of the series is the behind-the-scenes interviews and analysis of the series. Don’t look for sit-downs with William Shatner or Avery Brooks, but there is substantial footage of a mid-2010s interview with Leonard Nimoy.

And the series gives us a good picture of the role Lucille Ball, sitcom pioneer and Hollywood businesswoman, played in “Star Trek.”
