10 Star Trek Episodes That Were Banned
Make It 'No'.
Being a family-friendly show that usually tries to instill values of hope, cooperation, and goodwill to all species, Star Trek doesn't tend to court too much controversy. Indeed, the show's more notorious moments tend to arise in pursuit of pushing a noble social cause, or society simply not liking what's reflected back at it through the mirror of an episode.
