The Center Seat: 55 Years of Star Trek
It’s an eleven episode series of 45 minute longish episodes that go into all the details of the franchise up to about the TNG/DS9/VOY/ENT era with plenty of talking heads from the various series, though not many of the big names showed up for it. It’s interesting if you’ve not seen Trek documentaries before, and it’s still entertaining for those of us that have been around for a while.
