No, I agree with that and don't think anybody is arguing that. I think people are surprised by the look of the show that it is reporting to be one of the higher costing shows ever. You look at other shows that are listed in the most expensive ever, and it's either b/c of salaries (Friends, Frazier), period pieces which are pricey (Boardwalk Empire, The Crown), or they look a lot better (again, JMO) than this - GoT, Band of Brothers, etc..
A show I love, The Expanse, I would argue looks better than Madalorian and has a $5M/episode budget. I think people are just curious where the money is going if that price tag is accurate.
