The Fortean Times has been identifying more and more, recently, a trend to a sort of 1970s throwback aesthetic, as refracted through the memories of people who were children then. (Like you and me.) It's an aesthetic of a particular style of graphic design, and interior design, and architecture, and grainy videotapes of public announcement safety campaigns played in school, and slightly ratty posters cheerily saying things which are more alarming the more you think about it, and everything in burnt orange and mission brown and forest green and yellow bottle-bottom glass and corduroy.

Stranger Things is one manifestation of it, as are things like Scarfolk, and the reprint of the Usborne's World of the Unknown: Ghosts.

The Fortean Times has called it "The Haunted Generation", possibly after Scarfolk's use of "Hauntology" (= "The past, and elements of the past, returning as a ghost to inhabit the present")
