Some Trekkies are angry at Star Trek: Strange New Worlds for diving into Star Trek's biggest history problem. In The Original Series episode "Space Seed," Spock told the Enterprise crew that Khan Noonien Singh took power in 1992 and was sent into space in 1996. Strange New Worlds Season 2 fixed that, placing Khan in the near-future of the 21st Century. If this means the Prime Timeline no longer includes The Original Series, then that began with Star Trek: Voyager -- because in Voyager Season 3's "Future's End," the crew traveled back to 1996.
