For example , De Elizabeth of TeenVogue points out that Riverdale 's pilot episode was named `` River 's Edge '' after the 1986 film of the same name , and the season finale also takes its name from 1997 's The Sweet Hereafter .

References to the fictional setting of the Black Mirror episode `` San Junipero '' can be seen in viewed in season one as well as heard amongst dialogue in season two . </P>
