You should try Star Trek The Next Conversation. It’s very long and haphazard in its execution, but it’s entertaining; it’s don’t by people who are fans of Star Trek who also work in TV.
They made it through TNG, and are working on DS9. They’re also going through Voyager, Enterprise, Disco, Strange New Worls, and a bunch of Marvel movies on their patreon.
And , as far as I can tell, there’s no ads.
