Why isn't this show available streaming?

3 seasons, 67 episodes, Lance Henriksen in the lead role, and it covers a kind of mishmash of mystery/thriller, science fiction and supernatural/horror genres, as well as being sort of the same type of universe as the X-files.

This seems like a no-brainer for streaming. Above average overall, way above average considering the dreck on streaming services.

So what's the deal? It was on TV far enough into the home video era such that it shouldn't have too many weird rights issues, especially considering it was a Fox show.

All I can think of is that it was a 4:3 SD TV show, but that shouldn't be a huge issue.

You can't even buy it for streaming as far as I can tell, only the DVDs.
