On a somewhat related note, does not the proliferation of "reboots" suggest our culture has become stagnant, decadent, and given to self-reference? I think there is also some element of the totalitarian dogma of PC, and its related hypersensitivities, having effectively squelched good writing or at least the willingness to try new avenues. There is a subconscious desire for a return to the time "when (TV, movies, music, whatever) were good" and that might explain the enormous number of remakes/reboots currently active in TV and movies. "Retro" always has a certain foothold in popular culture, but it seems especially prominent now.
