My daughter and I really enjoyed the Disney's Animal Kingdom show and the Weird but True show.
I enjoyed "Mars Inside SpaceX" (but that's another "fandom" of mine, so YMMV) and the various Albert Lin shows. He's a little over the top, but the archeology topics are interesting. I haven't watched a lot of the geography shows, but I enjoyed the "Japan between Earth and Sky". It's like taking a helicopter tour of Japan. The "Drain the..." series is just silly, but there are nuggets of interest in some of them. And the James Cameron show where he thinks he's found Atlantis was facepalm-inducingly bad. So maybe watch that for the entertaining mockability.
Like I said, not everything was worth watching but I did anyway.
