Buffy Season 6 was an extremely strong and very strict revival of the the early 1600’s Life is a Dream wave (like, Quixote and The Tempest and L‘illusion Comique and Lo Fingido Verdadero and Doctor Faustus and La vida es sueño): failure of narrative + magic + illusion + pyrrhonian skepticism + melancholy + cyclicality + genre-switching + grief + metafiction + theatrum mundi.
