YMMV: Sealab 2020

  • Adaption Displacement: At the time many youngsters staying up late would have seen 2021, long before even knowing a 2020 episode.
    • Subverted of course if you were alive in the 70s, earlier 90s or now that both are equally available on DVD.
  • Complaining about Shows You Don't Watch: A frequent victim of this trope.
  • Surprisingly Improved Sequel: To the fans of 2021, the old show's more serious story style is seen as boring.
  • Vindicated by Reruns: On the flipside fans who can now see the whole thing on DVD, the more serious story style is taken to be more misunderstood and better than 2021's more comical stylyings.
