I guess there is a retro element to the endless torrent of Marvel / DC / et al superhero vehicles
A regressive or stagnant element in terms of character typology, motivation, fantasy, morality, narrative etc
Coupled - paradoxically - with absolutely ultra-modern state of the art powers being flexed in terms of the technical execution of these "children's entertainments" - the CGI and motion-capture, the 3-D camerawork, the sound design, the grading, the editing etc etc etc.
A parallel to my avant-lumpen theory about the most progressive or futuroid musical forms being coupled with politically regressive values and attitudes.
Technosonically in the future; emotionally-libidinally in the.... Middle Ages, really.
Codes of honor, warrior-masculinity, potlatch etc etc
Return of the saga, the legend, the epic, the allegorical etc etc
On the subject of heroics and heroism, I think also of this book
