There's an episode where they find a huge underwater pyramid that has ancient Greek writing on it. A character gets possessed and starts speaking Greek. It turns out it's The Temple of Minerva built by Neptune. Now if you had a thing for mythology, like I did, as a kid you probably notice those are the Roman names of the gods. And Minerva is a black woman. This is in the early 90s.
This "replacement rot" has been going on for a long time
I watched it when I was younger. I liked it at the time. One interesting point is they declared Colin Powel the current president and the Admiral had a signed picture of him. That was a pretty bold move given the time.
