Or maybe smearing of surface features is part of successful mating? These things change you know. Then there could be a ritual of reapplying the ritual scarification or surface electronics after the main event is over. These things are culturally as well as biologically determined and who am I to judge or guess what might be involved. Clearly more research is needed.
But we can certainly applaud these trends in body paint / surface electronics unless of course we are decrying this obvious objectification of women beneath a veneer of plot-driven character to obscure the latent or not so latent exploitation in action adventure comic-derived feature films.
Obviously we need more examples and more hands-on research in order to determine what is going on here. In the mean time, and in the absence of a certain condemnation, we can provisionally grant our approval and look forward to the future in this subgenre.
