I watched all three shows too, but never got around to the SG1 TV movies, so I’m not really up to speed with how it ended (Universe, the last show, didn’t give a lot of context about what was happening on earth aside from boring people’s personal lives).
Anyway, in the video they say they’ll make it completely accessible to newbies, or people who don’t like scifi, while somehow respecting the canon. Heard that before, so we’ll see. But at least it’s not a total reboot. I’m looking forward to seeing what we get.
