passage: Buffy the Vampire Slayer (season 6)
Joanna Robinson of "Vanity Fair" wrote on the 20th anniversary of the show's premiere that season 6, "a dark, unpopular chapter in the show's seven-year run...once its' most hated - has become its most important." Robinson praised the introduction of the Evil Trio, the much-maligned "Big Bad" villains for season 6, as presaging the later trend of "entitled, misogynistic rhetoric that rose to the surface during the Gamergate culture wars of 2014, and has seemingly infiltrated everything since—the 2016 presidential election included." She concluded, positively, that "It may lack some of the trademark zip of the show in its prime, and critics of the Dark Willow story line in particular are not wrong in their concerns. But with the luxury of historical context, Season 6 of Buffy carries more powerful resonance than any other moment in the show's history."
