Buck Rogers/YMMV

• Adaptation Displacement: The generation who grew up with the Gil Gerard TV series is far more familiar with that version than with the comic strip or film serials.
• Deader Than Disco: the TV series was the butt of many jokes throughout the eighties for being very 1970s, ironically because of its focus on disco era music and fashions. It picked up popularity again as something of a kitch retro classic in the nineties, however.
• Magnificent Bastard: "Killer" Kane in the comic strips. Suffered severe Villain Decay in the TV series, with he and Ardala essentially swapping roles.
• The Scrappy: Ah, Twiki.
• Unfortunate Implications: As far as the comic strip was concerned, apparently black people are extinct in the 25th century (at least, none are shown). White people, Asians (who aren't all uniformly bad guys), and Native Americans still exist in large numbers.
• Values Dissonance: where to start? The early novels consistently refer to adult women as 'girls' (although Buck as narrator regards them as equal to the men and notes that the women have significant fighting and leadership roles) and portray the Han as stereotypically decadent, making mention that their values were entirely contrary to those of 'the American race'.
