If Star Trek ever had a black sheep in the franchise, it was Deep Space Nine. The follow-up to The Next Generation premiered in 1993 and delivered a brilliant story that spanned for seven seasons. While most fans knew Star Trek to take place on a starship that explored different planets, aliens, and cultures, Deep Space Nine proved it could be something more. The series followed Commander Benjamin Sisko, a Starfleet officer who lost his wife in a Borg attack before taking command of the space station Deep Space Nine.
