It depends on what they take away as the lesson. Andor makes the case for being expansive and any character can hold their own show. It also gives a good idea of what a prequel should be. Sony should be taking notes for their discount MCU lol.
But I wouldn't blame Gilroy if other franchises screw it up. Same way I don't blame Chris Nolan for the origin reboot trend or Alan Moore for the darker shift in the 80s or Fiege for the interconnected franchise. They started a trend but I can't blame the screw ups on them.
