Storylines
The storylines generally revolved around morality plays on the evils of racism and bigotry using Newcomers as the discriminated minority. As fictional extraterrestrial immigrants, the Newcomers could stand in for social issues about African-Americans or Hispanics, as well as sexual minorities such as homosexuals, and would invert the usual expectations. For instance, during the run of the series, George became pregnant (the male of his species carrying the fetus for part of its gestation) and during much of the episode dialog included lines like, "If you females had to feel the pain we males feel during pregnancy, there wouldn't be any babies." The series offered social commentary by illustrating what it means to be human and the often bizarre rituals we observe.
