* BrokenBase: Regarding the eras. TheSeventies are well liked while TheNineties and TheEighties are polarizing. Maybe or maybe not related to nostalgia, and the shift in musical trends and genres. Either way discuss at your own risk.
** Also some hated the 90's, but not because they ''were'' the 90's, but because it never fully ''embraced'' the 90's. The 90's era never really fully embraced HipHop (neither did the 80's for that matter). It did marginally better with other urban genres like New Jack Swing. But over all the 90's was not a huge pop culture reference pool like the eighties, and seventies eras were. Essentially alienating the black MTV generation. Because of this people think this is what led to the show's down fall.
* EnsembleDarkhorse: Several, but the best known is Carol Song aka "the Asian chick with the hair".
* JumpTheShark: Most people point to Cornelius giving up hosting duties.
* MemeticMutation: ''THE '''SOOOOOOOOOOOOOOOOOOOOOOOOOOOOUL''' TRAIN!''
** Also parodied was Cornelius' tendency to sway when [=MCing=], lampshaded on ''Series/{{MADtv}}'' once.
* NeverLiveItDown: Although outlasting the genre by two decades, the show couldn't escape its connection to disco (particularly big bellbottoms and bigger Afros).
* OlderThanTheyThink: Carol Song had been a ''Soul Train'' Dancer since at least the late 1970s.
* ReplacementScrappy: After Don Cornelius stepped away from hosting, every subsequent host was tolerated at best by the fandom.
* TheScrappy: Any white male dancer in the ''Soul Train'' Line. Bro, give it up you can't dance.
** White women tended to avoid this Trope, holding their own on the dance floor.
** White singers were tolerated, but only a few of them (including EltonJohn, Michael [=McDonald=] and DavidBowie[[note]]hilariously, as he was transitioning to his aristocratic, "emotionless ''[[NaziNobleman Aryan]]'' [[{{Ubermensch}} superman]]" "Thin White Duke" phase[[/note]]) were deemed worthy.
