I can understand the figure a bit better for sense8 now, I suppose one thing the like of GOT has managed is to get location shots and studio costs down considerably using the EU including my own country. Something Brexit has really fucked up for us here in Northern Ireland.
I guess that the warchowski bros as producers definitely eat up the cash to an extent but perhaps they are using crew used to movie wages too, instead of talent in that area coming from TV mediums. Same from Luhrmann maybe. Which to me is bad business from Netflix but I suppose they just want quality and are willing to say "take my money," whatever the cost.
A lot of what it takes to make something look expensive is good colour correction (Top Gear and The Grand Tour are currently having a colour correction war) so I honestly think Netflix are being conned a bit by a couple of shows that look super expensive but cost buttons elsewhere. I'm not saying either of those two shows have scrimped at all, but I do think those figures are insanity for a show like The Get Down.
